Smartphone-Based Hearing Screening at Primary Health Care Clinics.
Objective: To evaluate the performance of smartphone-based hearing screening with the hearScreen(TM) application in terms of sensitivity, specificity, referral rates, and time efficiency at two primary health care clinics. Design: Nonprobability purposive sampling was used at both clinics. A total of 1236 participants (mean age: 37.8 +/- SD 17.9 and range 3 to 97 years; 71.3% female) were included in the final analysis. Participants were screened using the hearScreen(TM) application following a two-step screening protocol and diagnostic pure-tone audiometry to confirm hearing status. Results: Sensitivity and specificity for smartphone screening was 81.7 and 83.1%, respectively, with a positive and negative predictive value of 87.6 and 75.6%, respectively. Sex [[chi]2(1, N = 126) = 0.304, p > 0.05] and race [[chi]2(1, N = 126) = 0.169, p > 0.05)] had no significant effect on screening outcome for children while for adults age (p

Visual Temporal Acuity Is Related to Auditory Speech Perception Abilities in Cochlear Implant Users.
Objectives: Despite significant improvements in speech perception abilities following cochlear implantation, many prelingually deafened cochlear implant (CI) recipients continue to rely heavily on visual information to develop speech and language. Increased reliance on visual cues for understanding spoken language could lead to the development of unique audiovisual integration and visual-only processing abilities in these individuals. Brain imaging studies have demonstrated that good CI performers, as indexed by auditory-only speech perception abilities, have different patterns of visual cortex activation in response to visual and auditory stimuli as compared with poor CI performers. However, no studies have examined whether speech perception performance is related to any type of visual processing abilities following cochlear implantation. The purpose of the present study was to provide a preliminary examination of the relationship between clinical, auditory-only speech perception tests, and visual temporal acuity in prelingually deafened adult CI users. It was hypothesized that prelingually deafened CI users, who exhibit better (i.e., more acute) visual temporal processing abilities would demonstrate better auditory-only speech perception performance than those with poorer visual temporal acuity. Design: Ten prelingually deafened adult CI users were recruited for this study. Participants completed a visual temporal order judgment task to quantify visual temporal acuity. To assess auditory-only speech perception abilities, participants completed the consonant-nucleus-consonant word recognition test and the AzBio sentence recognition test. Results were analyzed using two-tailed partial Pearson correlations, Spearman's rho correlations, and independent samples t tests. Results: Visual temporal acuity was significantly correlated with auditory-only word and sentence recognition abilities. In addition, proficient CI users, as assessed via auditory-only speech perception performance, demonstrated significantly better visual temporal acuity than nonproficient CI users. Conclusions: These findings provide the first behavioral evidence that visual temporal acuity is related to post implantation CI proficiency as indexed by auditory-only speech perception performance. These preliminary data bring to light the possible future role of visual temporal acuity in predicting CI outcomes before implantation, as well as the possible utility of visual training methods in improving CI outcomes.

Midbrain Synchrony to Envelope Structure Supports Behavioral Sensitivity to Single-Formant Vowel-Like Sounds in Noise
Abstract
Vowels make a strong contribution to speech perception under natural conditions. Vowels are encoded in the auditory nerve primarily through neural synchrony to temporal fine structure and to envelope fluctuations rather than through average discharge rate. Neural synchrony is thought to contribute less to vowel coding in central auditory nuclei, consistent with more limited synchronization to fine structure and the emergence of average-rate coding of envelope fluctuations. However, this hypothesis is largely unexplored, especially in background noise. The present study examined coding mechanisms at the level of the midbrain that support behavioral sensitivity to simple vowel-like sounds using neurophysiological recordings and matched behavioral experiments in the budgerigar. Stimuli were harmonic tone complexes with energy concentrated at one spectral peak, or formant frequency, presented in quiet and in noise. Behavioral thresholds for formant-frequency discrimination decreased with increasing amplitude of stimulus envelope fluctuations, increased in noise, and were similar between budgerigars and humans. Multiunit recordings in awake birds showed that the midbrain encodes vowel-like sounds both through response synchrony to envelope structure and through average rate. Whereas neural discrimination thresholds based on either coding scheme were sufficient to support behavioral thresholds in quiet, only synchrony-based neural thresholds could account for behavioral thresholds in background noise. These results reveal an incomplete transformation to average-rate coding of vowel-like sounds in the midbrain. Model simulations suggest that this transformation emerges due to modulation tuning, which is shared between birds and mammals. Furthermore, the results underscore the behavioral relevance of envelope synchrony in the midbrain for detection of small differences in vowel formant frequency under real-world listening conditions.

Development and Technical Validation of the Mobile Based Assistive Listening System: A Smartphone-Based Remote Microphone
Purpose
The purpose of this research note is to describe the development and technical validation of the Mobile Based Assistive Listening System (MoBALS), a free-of-charge smartphone-based remote microphone application.
Method
MoBALS Version 1.0 was developed for Android (Version 2.1 or higher) and was coded with Java using Eclipse Indigo with the Android Software Development Kit. A Wi-Fi router with background traffic and 2 affordable smartphones were used for debugging and technical validation comprising, among other things, multicasting capability, data packet loss, and battery consumption.
Results
MoBALS requires at least 2 smartphones connected to the same Wi-Fi router for signal transmission and reception. Subscriber identity module cards or Internet connections are not needed. MoBALS can be used alone or connected to a hearing aid or cochlear implant via direct audio input. Maximum data packet loss was 99.28%, and minimum battery life was 5 hr. Other relevant design specifications and their implementation are described.
Conclusions
MoBALS performed as a remote microphone with enhanced accessibility features and avoids overhead expenses by using already-available and affordable technology. The further development and technical revalidation of MoBALS will be followed by clinical evaluation with persons with hearing impairment.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eoaR4Q

Hearing Device Manufacturers Call for Interoperability and Standardization of Internet and Audiology
Purpose
This article describes the perspectives of hearing device manufacturers regarding the exciting developments that the Internet makes possible. Specifically, it proposes to join forces toward interoperability and standardization of Internet and audiology.
Method
A summary of why such a collaborative effort is required is provided from historical and scientific perspectives. A roadmap toward interoperability and standardization is proposed.
Results
Information and communication technologies improve the flow of health care data and pave the way to better health care. However, hearing-related products, features, and services are notoriously heterogeneous and incompatible with other health care systems (no interoperability). Standardization is the process of developing and implementing technical standards (e.g., Noah hearing database). All parties involved in interoperability and standardization realize mutual gains by making mutually consistent decisions. De jure (officially endorsed) standards can be developed in collaboration with large national health care systems as well as spokespeople for hearing care professionals and hearing device users. The roadmap covers mutual collaboration; data privacy, security, and ownership; compliance with current regulations; scalability and modularity; and the scope of interoperability and standards.
Conclusions
We propose to join forces to pave the way to the interoperable Internet and audiology products, features, and services that the world needs.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eM3EOC

Can a Commercially Available Auditory Training Program Improve Audiovisual Speech Performance?
Purpose
The goal of this study was to determine whether hearing aids in combination with computer-based auditory training improve audiovisual (AV) performance compared with the use of hearing aids alone.
Method
Twenty-four participants were randomized into an experimental group (hearing aids plus ReadMyQuips [RMQ] training) and a control group (hearing aids only). The Multimodal Lexical Sentence Test for Adults (Kirk et al., 2012) was used to measure auditory-only (AO) and AV speech perception performance at three signal-to-noise ratios (SNRs). Participants were tested at the time of hearing aid fitting (pretest), after 4 weeks of hearing aid use (posttest I), and again after 4 weeks of RMQ training (posttest II).
Results
Results did not reveal an effect of training. As expected, interactions were found between (a) modality (AO vs. AV) and SNR and (b) test (pretest vs. posttests) and SNR.
Conclusion
Data do not show a significant effect of RMQ training on AO or AV performance as measured using the Multimodal Lexical Sentence Test for Adults.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eo7Xgv

Community-Based Intervention Determines Tele-Audiology Site Candidacy
Purpose
Sections of the community face barriers to accessing audiology services. The aim of this study was to assess the barriers faced by people in typically underserved community settings and to provide audiology services in their natural environment. Information gathered by questionnaire was used to determine each site's candidacy as a potential tele-audiology site.
Method
Sixty-three participants were recruited across 3 community sites that were identified as gathering places for individuals who experience barriers to accessing traditional clinical audiology services. Information about demographics and participant experience with barriers to access was gathered by a locally generated, self-administered questionnaire. Pure-tone air-conduction audiometric exams were performed on participants with an automated portable diagnostic audiometer. Afterward, the investigator provided counseling regarding hearing loss rehabilitation or hearing protection. Referrals were made when appropriate.
Results
Pure-tone averages were similar within sites but varied across sites. At least 30% of individuals at each site reported they wanted to visit the audiologist more often. Each site reported different principal barriers to access, among them transportation, motivation, and money. Eleven individuals were referred to the next level of care. Questionnaire results revealed special accommodations should be considered at each potential tele-audiology site.
Conclusion
The present study provided audiology services to individuals in their natural environment, identified many of the obstacles preventing individuals from pursuing traditional audiology services and provided information for the foundation of a tele-audiology practice.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eobf3e

Design Considerations for Internet-Delivered Self-Management Programs for Adults With Hearing Impairment
Purpose
Hearing impairment (HI) is a chronic condition; thus, even with treatment, residual participation restrictions and activity limitations typically remain. Individuals must learn to self-manage their HI. The purpose of this research note is to review components of successful Internet-based self-management programs and to evaluate group auditory rehabilitation (AR) programs with varying content, in order to make recommendations for the design of future Internet-based self-management programs.
Method
Effect sizes for changes in HI-specific quality of life following group AR activities from 4 published studies were calculated to determine if effect size varied systematically as a function of group activities. These findings are described using a self-management framework.
Results
Successful group AR activities include (a) psychosocial activities to promote role management, emotional management, and social support; (b) informational lectures and group discussion to promote education; (c) communication strategy exercises to promote self-efficacy and self-management skills; and (d) the inclusion of a frequent communication partner to promote social support and self-tailoring.
Conclusions
It is recommended that future Internet-based self-management programs focus on the mechanisms of social support and education to promote learning and self-management skills. Future research will determine if these AR activities may be implemented effectively via the Internet.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eob3kv

International Survey of Audiologists' Attitudes Toward Telehealth
Purpose
A better understanding of the attitudes of audiologists toward teleaudiology and their willingness to use teleaudiology is required to progress the application of teleaudiology technologies and services into clinical practice. Audiologists around the world were surveyed on their attitudes toward teleaudiology and their willingness to use it.
Method
An online survey was sent to audiologists through professional associations' mailing lists. The survey included questions on the use of computer and video-conferencing technologies, awareness and previous use of teleaudiology, and willingness to use teleaudiology.
Results
Responses were provided by 269 people from 28 different countries, representing a wide cross-section of experience, qualification, and work settings; 77.8% of respondents were women. Almost all respondents had used PC-based video-conferencing; most had used related technologies and reported positive attitudes toward using these. However, less than 25% had used teleaudiology.
Conclusions
Despite positive attitudes toward telehealth and associated technology, the low number of audiologists who have used teleaudiology for services indicates limited clinical adoption.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eM61RA

Use and Mediating Effect of Interactive Design Features in Audiology Rehabilitation and Self-Management Internet-Based Interventions
Purpose
The purpose of this study is to explore the presence of key interactive design features across Internet-based audiology rehabilitation and self-management interventions, and whether there is evidence of them mediating effects of the intervention.
Method
Adult audiology interventions relevant to this review were identified through a literature search in Google Scholar and a hand search of key journals. Four key interactive design features that have been proposed to mediate the effects of Internet-based health interventions were reported for each intervention: social context and support, contacts with the intervention, tailoring, and self-management.
Results
Five interventions were identified as representative examples of work in the field. Social context and support and contacts with the intervention were provided in most interventions, mainly through clinician guidance. Only 1 intervention utilized tailoring to personalize intervention content to individual users, but use was minimal. Self-management features were also used in all interventions but the precise nature of these features was poorly reported.
Conclusion
Future studies should assess the optimal dose and combinations of intervention features for maximizing efficacy in audiology intervention. To be specific, the role of tailoring should be explored, which has been identified as a potential mediator of intervention outcome in the wider e-health literature.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eob73P

Internet Competency Predicts Practical Hearing Aid Knowledge and Skills in First-Time Hearing Aid Users
Purpose
The purpose of the study was to assess whether Internet competency predicted practical hearing aid knowledge and handling skills in first-time hearing aid users.
Method
The design was a prospective, randomized controlled trial of a multimedia educational intervention consisting of interactive video tutorials (or reusable learning objects [RLOs]). RLOs were delivered through DVD for TV or PC, and online. Internet competency was measured at the hearing aid fitting appointment, whereas hearing aid knowledge and practical handling skills were assessed 6 weeks postfitting.
Results
Internet competency predicted practical hearing aid knowledge and handling skills, controlling for age, hearing sensitivity, educational status, and gender for the group that received the RLOs. Internet competency was inversely related to the number of times the RLOs were watched.
Conclusion
Associations between Internet competency and practical hearing aid knowledge, handling skills, and watching the RLOs fewer times may have arisen because of improved self-efficacy. Therefore, first-time hearing aid users who are more competent Internet users may be better equipped to apply newly learned information to effectively manage their hearing loss.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eM3zue

Usability and Online Audiological Rehabilitation
Purpose
This paper describes the results from the iterative development and usability testing of an online audiological rehabilitation (OAR) program. The OAR was based on previous experience with Internet interventions and OAR.
Method
The described OAR consisted of weekly learning modules, each of which had a specific topic and contained information and learning activities. A virtual coach, a trained audiologist, led the participants through the modules. The participants' feedback was collected using the “think-aloud” method in which the participants gave their feedback in a structured manner.
Results
The early findings from the first version of the OAR showed that participants had difficulty navigating the system. As a result of the usability testing, a second major edition of the OAR program was developed, and the participants found it easier to manage and that it enhanced the learning experience. The participants appreciated the testimonial videos as well as the option to study more in-depth material for a given subject.
Conclusions
The early findings from the usability test of the program provided useful information as to how content can be developed and delivered for optimal user accessibility within the scope of OAR.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eo9DGT

Online Data Collection to Evaluate a Theoretical Cognitive Model of Tinnitus
Purpose
The purpose of this article is to describe data collection considerations, methods, and response rates for a survey available both online and on paper. Methodological issues in the design of online data collection, and advantages and disadvantages of different data collection methods are discussed.
Method
A survey was compiled that included 9 full or partial clinical questionnaires designed to measure different components relevant to tinnitus distress. It was completed once by 342 members of the public with tinnitus. Respondents could choose whether to complete the survey online or on paper.
Results
Ninety-five percent of participants chose to complete the survey online. The advantages of an online self-administered questionnaire include low numbers of unanswered questions, convenience (particularly in a longer survey such as this), a fast return rate, and reduced expense. Age emerged as an important variable, with those opting to complete the paper-based version of the survey being older.
Conclusions
Online data collection has several advantages to both participants and researchers. However, cross-sectional studies such as that presented here should also offer paper questionnaires to avoid excluding certain subgroups of the population. Ethics and reporting guidelines for Internet-delivered questionnaire studies are available. These can usefully inform study design and guide high-quality reporting.from #Audiology via xlomafota13 on Inoreader http://ift.tt/2eM7440

Design Considerations for Internet-Delivered Self-Management Programs for Adults With Hearing Impairment
Purpose
Hearing impairment (HI) is a chronic condition; thus, even with treatment, residual participation restrictions and activity limitations typically remain. Individuals must learn to self-manage their HI. The purpose of this research note is to review components of successful Internet-based self-management programs and to evaluate group auditory rehabilitation (AR) programs with varying content, in order to make recommendations for the design of future Internet-based self-management programs.
Method
Effect sizes for changes in HI-specific quality of life following group AR activities from 4 published studies were calculated to determine if effect size varied systematically as a function of group activities. These findings are described using a self-management framework.
Results
Successful group AR activities include (a) psychosocial activities to promote role management, emotional management, and social support; (b) informational lectures and group discussion to promote education; (c) communication strategy exercises to promote self-efficacy and self-management skills; and (d) the inclusion of a frequent communication partner to promote social support and self-tailoring.
Conclusions
It is recommended that future Internet-based self-management programs focus on the mechanisms of social support and education to promote learning and self-management skills. Future research will determine if these AR activities may be implemented effectively via the Internet.from #Audiology via ola Kala on Inoreader http://ift.tt/2eob3kv

International Survey of Audiologists' Attitudes Toward Telehealth
Purpose
A better understanding of the attitudes of audiologists toward teleaudiology and their willingness to use teleaudiology is required to progress the application of teleaudiology technologies and services into clinical practice. Audiologists around the world were surveyed on their attitudes toward teleaudiology and their willingness to use it.
Method
An online survey was sent to audiologists through professional associations' mailing lists. The survey included questions on the use of computer and video-conferencing technologies, awareness and previous use of teleaudiology, and willingness to use teleaudiology.
Results
Responses were provided by 269 people from 28 different countries, representing a wide cross-section of experience, qualification, and work settings; 77.8% of respondents were women. Almost all respondents had used PC-based video-conferencing; most had used related technologies and reported positive attitudes toward using these. However, less than 25% had used teleaudiology.
Conclusions
Despite positive attitudes toward telehealth and associated technology, the low number of audiologists who have used teleaudiology for services indicates limited clinical adoption.from #Audiology via ola Kala on Inoreader http://ift.tt/2eM61RA

Use and Mediating Effect of Interactive Design Features in Audiology Rehabilitation and Self-Management Internet-Based Interventions
Purpose
The purpose of this study is to explore the presence of key interactive design features across Internet-based audiology rehabilitation and self-management interventions, and whether there is evidence of them mediating effects of the intervention.
Method
Adult audiology interventions relevant to this review were identified through a literature search in Google Scholar and a hand search of key journals. Four key interactive design features that have been proposed to mediate the effects of Internet-based health interventions were reported for each intervention: social context and support, contacts with the intervention, tailoring, and self-management.
Results
Five interventions were identified as representative examples of work in the field. Social context and support and contacts with the intervention were provided in most interventions, mainly through clinician guidance. Only 1 intervention utilized tailoring to personalize intervention content to individual users, but use was minimal. Self-management features were also used in all interventions but the precise nature of these features was poorly reported.
Conclusion
Future studies should assess the optimal dose and combinations of intervention features for maximizing efficacy in audiology intervention. To be specific, the role of tailoring should be explored, which has been identified as a potential mediator of intervention outcome in the wider e-health literature.from #Audiology via ola Kala on Inoreader http://ift.tt/2eob73P

Internet Competency Predicts Practical Hearing Aid Knowledge and Skills in First-Time Hearing Aid Users
Purpose
The purpose of the study was to assess whether Internet competency predicted practical hearing aid knowledge and handling skills in first-time hearing aid users.
Method
The design was a prospective, randomized controlled trial of a multimedia educational intervention consisting of interactive video tutorials (or reusable learning objects [RLOs]). RLOs were delivered through DVD for TV or PC, and online. Internet competency was measured at the hearing aid fitting appointment, whereas hearing aid knowledge and practical handling skills were assessed 6 weeks postfitting.
Results
Internet competency predicted practical hearing aid knowledge and handling skills, controlling for age, hearing sensitivity, educational status, and gender for the group that received the RLOs. Internet competency was inversely related to the number of times the RLOs were watched.
Conclusion
Associations between Internet competency and practical hearing aid knowledge, handling skills, and watching the RLOs fewer times may have arisen because of improved self-efficacy. Therefore, first-time hearing aid users who are more competent Internet users may be better equipped to apply newly learned information to effectively manage their hearing loss.from #Audiology via ola Kala on Inoreader http://ift.tt/2eM3zue

Usability and Online Audiological Rehabilitation
Purpose
This paper describes the results from the iterative development and usability testing of an online audiological rehabilitation (OAR) program. The OAR was based on previous experience with Internet interventions and OAR.
Method
The described OAR consisted of weekly learning modules, each of which had a specific topic and contained information and learning activities. A virtual coach, a trained audiologist, led the participants through the modules. The participants' feedback was collected using the “think-aloud” method in which the participants gave their feedback in a structured manner.
Results
The early findings from the first version of the OAR showed that participants had difficulty navigating the system. As a result of the usability testing, a second major edition of the OAR program was developed, and the participants found it easier to manage and that it enhanced the learning experience. The participants appreciated the testimonial videos as well as the option to study more in-depth material for a given subject.
Conclusions
The early findings from the usability test of the program provided useful information as to how content can be developed and delivered for optimal user accessibility within the scope of OAR.from #Audiology via ola Kala on Inoreader http://ift.tt/2eo9DGT

Online Data Collection to Evaluate a Theoretical Cognitive Model of Tinnitus
Purpose
The purpose of this article is to describe data collection considerations, methods, and response rates for a survey available both online and on paper. Methodological issues in the design of online data collection, and advantages and disadvantages of different data collection methods are discussed.
Method
A survey was compiled that included 9 full or partial clinical questionnaires designed to measure different components relevant to tinnitus distress. It was completed once by 342 members of the public with tinnitus. Respondents could choose whether to complete the survey online or on paper.
Results
Ninety-five percent of participants chose to complete the survey online. The advantages of an online self-administered questionnaire include low numbers of unanswered questions, convenience (particularly in a longer survey such as this), a fast return rate, and reduced expense. Age emerged as an important variable, with those opting to complete the paper-based version of the survey being older.
Conclusions
Online data collection has several advantages to both participants and researchers. However, cross-sectional studies such as that presented here should also offer paper questionnaires to avoid excluding certain subgroups of the population. Ethics and reporting guidelines for Internet-delivered questionnaire studies are available. These can usefully inform study design and guide high-quality reporting.from #Audiology via ola Kala on Inoreader http://ift.tt/2eM7440

Development and Technical Validation of the Mobile Based Assistive Listening System: A Smartphone-Based Remote Microphone
Purpose
The purpose of this research note is to describe the development and technical validation of the Mobile Based Assistive Listening System (MoBALS), a free-of-charge smartphone-based remote microphone application.
Method
MoBALS Version 1.0 was developed for Android (Version 2.1 or higher) and was coded with Java using Eclipse Indigo with the Android Software Development Kit. A Wi-Fi router with background traffic and 2 affordable smartphones were used for debugging and technical validation comprising, among other things, multicasting capability, data packet loss, and battery consumption.
Results
MoBALS requires at least 2 smartphones connected to the same Wi-Fi router for signal transmission and reception. Subscriber identity module cards or Internet connections are not needed. MoBALS can be used alone or connected to a hearing aid or cochlear implant via direct audio input. Maximum data packet loss was 99.28%, and minimum battery life was 5 hr. Other relevant design specifications and their implementation are described.
Conclusions
MoBALS performed as a remote microphone with enhanced accessibility features and avoids overhead expenses by using already-available and affordable technology. The further development and technical revalidation of MoBALS will be followed by clinical evaluation with persons with hearing impairment.from #Audiology via ola Kala on Inoreader http://ift.tt/2eoaR4Q

Hearing Device Manufacturers Call for Interoperability and Standardization of Internet and Audiology
Purpose
This article describes the perspectives of hearing device manufacturers regarding the exciting developments that the Internet makes possible. Specifically, it proposes to join forces toward interoperability and standardization of Internet and audiology.
Method
A summary of why such a collaborative effort is required is provided from historical and scientific perspectives. A roadmap toward interoperability and standardization is proposed.
Results
Information and communication technologies improve the flow of health care data and pave the way to better health care. However, hearing-related products, features, and services are notoriously heterogeneous and incompatible with other health care systems (no interoperability). Standardization is the process of developing and implementing technical standards (e.g., Noah hearing database). All parties involved in interoperability and standardization realize mutual gains by making mutually consistent decisions. De jure (officially endorsed) standards can be developed in collaboration with large national health care systems as well as spokespeople for hearing care professionals and hearing device users. The roadmap covers mutual collaboration; data privacy, security, and ownership; compliance with current regulations; scalability and modularity; and the scope of interoperability and standards.
Conclusions
We propose to join forces to pave the way to the interoperable Internet and audiology products, features, and services that the world needs.from #Audiology via ola Kala on Inoreader http://ift.tt/2eM3EOC

Can a Commercially Available Auditory Training Program Improve Audiovisual Speech Performance?
Purpose
The goal of this study was to determine whether hearing aids in combination with computer-based auditory training improve audiovisual (AV) performance compared with the use of hearing aids alone.
Method
Twenty-four participants were randomized into an experimental group (hearing aids plus ReadMyQuips [RMQ] training) and a control group (hearing aids only). The Multimodal Lexical Sentence Test for Adults (Kirk et al., 2012) was used to measure auditory-only (AO) and AV speech perception performance at three signal-to-noise ratios (SNRs). Participants were tested at the time of hearing aid fitting (pretest), after 4 weeks of hearing aid use (posttest I), and again after 4 weeks of RMQ training (posttest II).
Results
Results did not reveal an effect of training. As expected, interactions were found between (a) modality (AO vs. AV) and SNR and (b) test (pretest vs. posttests) and SNR.
Conclusion
Data do not show a significant effect of RMQ training on AO or AV performance as measured using the Multimodal Lexical Sentence Test for Adults.from #Audiology via ola Kala on Inoreader http://ift.tt/2eo7Xgv

Community-Based Intervention Determines Tele-Audiology Site Candidacy
Purpose
Sections of the community face barriers to accessing audiology services. The aim of this study was to assess the barriers faced by people in typically underserved community settings and to provide audiology services in their natural environment. Information gathered by questionnaire was used to determine each site's candidacy as a potential tele-audiology site.
Method
Sixty-three participants were recruited across 3 community sites that were identified as gathering places for individuals who experience barriers to accessing traditional clinical audiology services. Information about demographics and participant experience with barriers to access was gathered by a locally generated, self-administered questionnaire. Pure-tone air-conduction audiometric exams were performed on participants with an automated portable diagnostic audiometer. Afterward, the investigator provided counseling regarding hearing loss rehabilitation or hearing protection. Referrals were made when appropriate.
Results
Pure-tone averages were similar within sites but varied across sites. At least 30% of individuals at each site reported they wanted to visit the audiologist more often. Each site reported different principal barriers to access, among them transportation, motivation, and money. Eleven individuals were referred to the next level of care. Questionnaire results revealed special accommodations should be considered at each potential tele-audiology site.
Conclusion
The present study provided audiology services to individuals in their natural environment, identified many of the obstacles preventing individuals from pursuing traditional audiology services and provided information for the foundation of a tele-audiology practice.from #Audiology via ola Kala on Inoreader http://ift.tt/2eobf3e

Have Cochlear Implant, Won't Have to Travel: Introducing Telemedicine to People Using Cochlear Implants
Purpose
This research note describes a planned project to design, implement, and evaluate remote care for adults using cochlear implants and compare their outcomes with those of individuals following the standard care pathway.
Method
Sixty people with cochlear implants will be recruited and randomized to either the remote care group or a control group. The remote care group will use new tools for 6 months: remote and self-monitoring, self-adjustment of device, and a personalized online support tool. The main outcome measure is patient empowerment, with secondary outcomes of stability in hearing and quality of life, patient and clinician preference, and use of clinic resources.
Conclusion
The clinical trial ends in summer 2016. Remote care may offer a viable method of follow-up for some adults with cochlear implants.from #Audiology via ola Kala on Inoreader http://ift.tt/2eM4XwY

La verificación empírica de modelos de conversión acústico-fonémica es una necesidad de la práctica de la neurolingüística en cualquier contexto para optimizar la explicación del patrón neurocognitivo de pacientes con alteraciones del procesamiento preléxico. Por tal razón, en esta investigación se caracterizan los procesos de conversión acústico-fonémica en pacientes hispanohablantes, con el objetivo de obtener y acumular evidencias empíricas que permitan verificar en esta población lingüística el modelo de procesamiento preléxico más aceptado actualmente. Para ello se realizó un estudio descriptivo-transversal, con la participación de 72 pacientes con afasia de comprensión pertenecientes a los Servicios de Logofoniatría de la ciudad de Santiago de Cuba, con edades de 20 a 65 años, y entre 60 y 180 días de recuperación del daño cerebral. Estos fueron sometidos al Test de discriminación fonológica, que es una adaptación local de la «Prueba de discriminación» del Test DIFO de Benedet y Cortés-del-Solar. Se obtuvo que las alteraciones del procesamiento de las características distintivas de los sonidos del habla se distinguen de las alteraciones de la integración perceptual de fonemas. En el primer caso, se registran fallos estables en la ejecución de tareas que implican el procesamiento de unos u otros rasgos distintivos de los sonidos consonánticos del habla, mientras se conserva el procesamiento de rasgos distintivos de los sonidos vocálicos, y viceversa. En el segundo caso, se observan fallos en el procesamiento, tanto de todos los rasgos distintivos de los sonidos consonánticos del habla, como de los rasgos distintivos de los sonidos vocálicos.The empirical verification of prelexical processing models is necessary for the neurolinguistic practices in any context for optimizing the explanations of neurocognitive model in aphasic patients with disorder in prelexical processing. For this reason, the present investigation shows the characterization of acoustic-phonemic conversion process in aphasic hispanophone patients. The study was executed with the purpose to accumulate and to obtain empirical evidences in this linguistic population, for the practical verification of the most accepted prelexical processing model. A descriptive-transversal study was conducted with the participation of 72 patients with sensitive aphasia, localized in the Phoniatry Services of Santiago de Cuba City, with ages between 20 and 65 years, and not more of 60 to 180 days of brain injury recovery period. The participants performed the Test de discriminación fonológica, that is a contextual adaptation of the task «Prueba de discriminación» of the Test DIFO of Benedet and Cortés-del-Solar. Results revealed that disorders in distinctive characteristics of speech sounds processing are different of phoneme perceptual integration disorders. In the first, affectation in the execution of tasks that implies the processing of some distinctive characteristics of consonant speech sounds was recorded, whereas the processing of other distinctive characteristics of vowel speech sounds are preserved. In the second affectation in the processing of all distinctive characteristics of speech sounds was observed.
