(Central) Auditory Processing Disorder Grand Rounds: Multiple Cases, Multiple Causes, Multiple Outcomes

Purpose
The purpose of this article was to provide multiple examples of how (central) auditory processing disorder ([C]APD) is being evaluated and treated at various audiology clinics throughout the United States.
Method
The authors present 5 cases highlighting the diagnosis and treatment of (C)APD in children and adults. Similarities and differences between these cases have been showcased through detailed histories, evaluation protocol, and treatment options. When possible, the rationale for evaluation procedures and intervention processes were described and compared with guidelines and findings within the literature.
Results and Conclusions
These cases illustrate the varied processes and clinical protocols by which children and adults are evaluated, diagnosed, counseled, and treated for (C)APD. In addition, similarities and differences between the referral source, evaluation team, developmental history, comorbidities, test battery, recommendations, and remediations were described. The multiple clinic sites, diversity of clinical philosophies, variety of test measures, and diversity of patient populations make these cases ideal for showcasing the assortment of methodologies used with patients who present with histories and characteristics consistent with (C)APD.

Evaluating Random Error in Clinician-Administered Surveys: Theoretical Considerations and Clinical Applications of Interobserver Reliability and Agreement

Purpose
The purpose of this study is to raise awareness of interobserver concordance and the differences between interobserver reliability and agreement when evaluating the responsiveness of a clinician-administered survey and, specifically, to demonstrate the clinical implications of data types (nominal/categorical, ordinal, interval, or ratio) and statistical index selection (for example, Cohen's kappa, Krippendorff's alpha, or interclass correlation).
Methods
In this prospective cohort study, 3 clinical audiologists, who were masked to each other's scores, administered the Practical Hearing Aid Skills Test–Revised to 18 adult owners of hearing aids. Interobserver concordance was examined using a range of reliability and agreement statistical indices.
Results
The importance of selecting statistical measures of concordance was demonstrated with a worked example, wherein the level of interobserver concordance achieved varied from “no agreement” to “almost perfect agreement” depending on data types and statistical index selected.
Conclusions
This study demonstrates that the methodology used to evaluate survey score concordance can influence the statistical results obtained and thus affect clinical interpretations.

Automatic Speech Recognition Predicts Speech Intelligibility and Comprehension for Listeners With Simulated Age-Related Hearing Loss

Purpose
The purpose of this article is to assess speech processing for listeners with simulated age-related hearing loss (ARHL) and to investigate whether the observed performance can be replicated using an automatic speech recognition (ASR) system. The long-term goal of this research is to develop a system that will assist audiologists/hearing-aid dispensers in the fine-tuning of hearing aids.
Method
Sixty young participants with normal hearing listened to speech materials mimicking the perceptual consequences of ARHL at different levels of severity. Two intelligibility tests (repetition of words and sentences) and 1 comprehension test (responding to oral commands by moving virtual objects) were administered. Several language models were developed and used by the ASR system in order to fit human performances.
Results
Strong significant positive correlations were observed between human and ASR scores, with coefficients up to .99. However, the spectral smearing used to simulate losses in frequency selectivity caused larger declines in ASR performance than in human performance.
Conclusion
Both intelligibility and comprehension scores for listeners with simulated ARHL are highly correlated with the performances of an ASR-based system. In the future, it needs to be determined if the ASR system is similarly successful in predicting speech processing in noise and by older people with ARHL.
