Computerized Auditory Training in Adults with Hearing Loss: An Examination of Clear-Customized Learning Exercises for Aural Rehabilitation

Abstract

Although hearing aids are the primary intervention method used by individuals with hearing loss, hearing aids alone may not ensure successful communication, and the use of auditory training can improve listening outcomes. Technological advances and limited access to services have increased the computerization of auditory training. The purpose of this research project is to examine a computerized auditory training program, clEAR- customized learning: Exercises for Aural Rehabilitation. This investigation should determine whether completing clEAR improves an individual's ability to listen in noise. Randomization occurred by dividing participants into two randomly assigned groups. The experimental group completed the clEAR program, and the control group engaged with a language-based mobile application. The pre-test evaluated participants' ability listening in noise by completing a self-questionnaire (Abbreviated Profile of Hearing Aid Benefit- APHAB) and speech-in-noise testing with recorded speech materials. After completing an assigned program or app for two months, participants attended post-testing, which used the same protocol as pre-testing. This study investigated the change from pre-test to post-test scores in both speech- in- noise performance and perceived benefit in reverberation, background noise, aversiveness to sound, and ease of communication. Researchers found that compared to the language-based application, completing clEAR for two months improved participant's perceived benefit in reverberant conditions. We found no statistically significant change in other measures. The discrepancies in findings highlight the importance of conducting independent external validation for auditory training programs. This study underscores the need for further investigation of clEAR-customized learning: Exercises for Aural Rehabilitation because the program may not improve listening in noise. The sample size and duration may negatively affect this pilot program's results.
