Objectives: Bilateral cochlear implants (BI-CIs) are intended to improve sound localization and speech understanding in the presence of interfering sounds. For normal-hearing listeners, improved speech understanding in the presence of interfering sounds can be achieved with monaural head shadow and binaural unmasking. While some BI-CI listeners experience binaural unmasking under certain testing conditions, others appear to not. This study tested a group of BI-CI users with hearing histories that have been linked to poor binaural processing-early onset of deafness or long duration of deafness in just one ear. We predicted that these listeners would experience the opposite of binaural unmasking (i.e., contralateral interference) when trying to understand speech in the presence of a competing talker. Design: Nine adult BI-CI users who were deafened early in life or had an asymmetric hearing history (e.g., a much longer duration of deafness in one ear) participated in this study. The coordinate response measure corpus was used to assess speech understanding for a male target talker in quiet or in the presence of one male competing talker. Experiment 1 measured binaural unmasking in a paradigm that provided no head-shadow component. The target was always presented monaurally, while the interferer was presented either monaurally or diotically. Experiment 2 measured spatial release from masking in a paradigm that included both a head-shadow component and possible binaural-unmasking component. Nonindividualized head-related transfer functions were used to simulate talker locations in the front or 90[degrees] to the left or right. Results: In experiment 1, all nine listeners experienced contralateral interference (9 dB on average). Four listeners demonstrated roughly symmetric contralateral interference; five listeners experienced asymmetrical contralateral interference. In experiment 2, the listeners experienced only 1 dB of spatial release from masking on average; this small amount was possibly a result of the contralateral interference observed in experiment 1. The results were best explained by individual differences in speech understanding in quiet, which significantly correlated with the duration of deafness in the ipsilateral ear. Specifically, instances of asymmetrical contralateral interference could correspond to asymmetrical hearing histories. Conclusions: Bilateral cochlear implantation should provide a hearing benefit to the recipient. For the BI-CI listeners specifically recruited for this study, there seems to be a conflict with processing the auditory information across the two ears, which produced the opposite of the desired hearing benefit. This suggests that there may be a subset of potential BI-CI users for whom contralateral interference offsets much of the potential head-shadow benefit. If so, earlier implantation in the second implanted ear might have produced larger binaural benefits, which is important information for clinicians advising patients considering bilateral implantation.

Beyond Sentences: Using the Expression, Reception, and Recall of Narratives Instrument to Assess Communication in School-Aged Children With Autism Spectrum Disorder
Purpose
Impairments in the social use of language are universal in autism spectrum disorder (ASD), but few standardized measures evaluate communication skills above the level of individual words or sentences. This study evaluated the Expression, Reception, and Recall of Narrative Instrument (ERRNI; Bishop, 2004) to determine its contribution to assessing language and communicative impairment beyond the sentence level in children with ASD.
Method
A battery of assessments, including measures of cognition, language, pragmatics, severity of autism symptoms, and adaptive functioning, was administered to 74 8- to 9-year-old intellectually able children with ASD.
Results
Average performance on the ERRNI was significantly poorer than on the Clinical Evaluation of Language Fundamentals–Fourth Edition (CELF-4). In addition, ERRNI scores reflecting the number and quality of relevant story components included in the participants' narratives were significantly positively related to scores on measures of nonverbal cognitive skill, language, and everyday adaptive communication, and significantly negatively correlated with the severity of affective autism symptoms.
Conclusion
Results suggest that the ERRNI reveals discourse impairments that may not be identified by measures that focus on individual words and sentences. Overall, the ERRNI provides a useful measure of communicative skill beyond the sentence level in school-aged children with ASD.from #Audiology via ola Kala on Inoreader http://article/doi/10.1044/2017_JSLHR-L-16-0168/2648607/Beyond-Sentences-Using-the-Expression-Reception

Glottal Aerodynamic Measures in Women With Phonotraumatic and Nonphonotraumatic Vocal Hyperfunction
Purpose
The purpose of this study was to determine the validity of preliminary reports showing that glottal aerodynamic measures can identify pathophysiological phonatory mechanisms for phonotraumatic and nonphonotraumatic vocal hyperfunction, which are each distinctly different from normal vocal function.
Method
Glottal aerodynamic measures (estimates of subglottal air pressure, peak-to-peak airflow, maximum flow declination rate, and open quotient) were obtained noninvasively using a pneumotachograph mask with an intraoral pressure catheter in 16 women with organic vocal fold lesions, 16 women with muscle tension dysphonia, and 2 associated matched control groups with normal voices. Subjects produced /pae/ syllable strings from which glottal airflow was estimated using inverse filtering during /ae/ vowels, and subglottal pressure was estimated during /p/ closures. All measures were normalized for sound pressure level (SPL) and statistically tested for differences between patient and control groups.
Results
All SPL-normalized measures were significantly lower in the phonotraumatic group as compared with measures in its control group. For the nonphonotraumatic group, only SPL-normalized subglottal pressure and open quotient were significantly lower than measures in its control group.
Conclusions
Results of this study confirm previous hypotheses and preliminary results indicating that SPL-normalized estimates of glottal aerodynamic measures can be used to describe the different pathophysiological phonatory mechanisms associated with phonotraumatic and nonphonotraumatic vocal hyperfunction.from #Audiology via ola Kala on Inoreader http://article/doi/10.1044/2017_JSLHR-S-16-0337/2648608/Glottal-Aerodynamic-Measures-in-Women-With

Speech Understanding in Noise by Patients With Cochlear Implants Using a Monaural Adaptive Beamformer
Purpose
The aim of this experiment was to compare, for patients with cochlear implants (CIs), the improvement for speech understanding in noise provided by a monaural adaptive beamformer and for two interventions that produced bilateral input (i.e., bilateral CIs and hearing preservation [HP] surgery).
Method
Speech understanding scores for sentences were obtained for 10 listeners fit with a single CI. The listeners were tested with and without beamformer activated in a “cocktail party” environment with spatially separated target and maskers. Data for 10 listeners with bilateral CIs and 8 listeners with HP CIs were taken from Loiselle, Dorman, Yost, Cook, and Gifford (2016), who used the same test protocol.
Results
The use of the beamformer resulted in a 31 percentage point improvement in performance; in bilateral CIs, an 18 percentage point improvement; and in HP CIs, a 20 percentage point improvement.
Conclusion
A monaural adaptive beamformer can produce an improvement in speech understanding in a complex noise environment that is equal to, or greater than, the improvement produced by bilateral CIs and HP surgery.from #Audiology via ola Kala on Inoreader http://article/doi/10.1044/2017_JSLHR-H-16-0312/2647807/Speech-Understanding-in-Noise-by-Patients-With

New Study Brings Cognitive Hearing Aids Closer to Reality
An end-to-end system that monitors the brain activity of hearing-impaired individuals to enhance speech intelligibility has been developed at the Columbia University School of Engineering and Applied Science, bringing cognitive hearing aids one step closer to reality (J Neural Eng. 2017). The system, which combines the latest single-channel automatic speech-separation algorithms into the auditory attention-decoding platform, automatically separates the individual speakers in the mixture it receives, and determines which speaker is being listened to using the listener's neural signals. It then amplifies the attended speaker's voice to assist the listener. The process is completed in less than 10 seconds.
This approach removes the limitations of existing methods for producing clean sound sources and sound amplification. The system alleviates the spatial separation requirements of multi-channel methods, and can be used in tandem with beamforming methods for optimal source separation. The researchers said "this work will move the field toward realistic hearing aid devices that can automatically and dynamically track a user's direction of attention, and amplify an attended speaker."

Introducing ReSound LiNX 3D: The Future of Smart Hearing
I'm pleased to be able to introduce you to our latest product, ReSound LiNX 3D. Several years ago, we made a decision to go down a different wireless technology path than our competitors, and with good reason: wireless accessories and wireless systems were cumbersome and not widely used. Hearing aid users were required to wear something around their neck, they were bulky and not very discreet. In 2008, when we were looking into developing a wireless system, we knew that 2.4 GHz would be the way of the future, and we decided to develop our wireless at 2.4 GHz.
