Purpose: Directional microphone systems are typically used to improve hearing aid users' understanding of speech in noise. However, directional microphones also increase internal hearing aid noise. The purpose of this study was to investigate how varying directional microphone bandwidth affected listening preference and speech-in-noise performance. Method: Ten participants with normal hearing and 10 participants with hearing impairment compared internal noise levels between hearing aid memories with 4 different microphone modes: omnidirectional, full directional, high-frequency directionality with directional processing above 900 Hz, and high-frequency directionality with directional processing above 2000 Hz...

Purpose: The auditory brainstem response (ABR) is a powerful tool for making clinical decisions about the presence, degree, and type of hearing loss in individuals in whom behavioral hearing thresholds cannot be obtained or are not reliable. Although the test is objective, interpretation of the results is subjective. Method: This review provides information about evidence-based criteria, suggested by the 2013 Newborn Hearing Screening Program guidelines, and the use of cross-check methods for making valid interpretations about hearing status from ABR recordings...

Purpose: This study explored experiences of self-stigma among older persons with age-related hearing loss (ARHL) using Corrigan's conceptualization of self-stigma process formation and the attribution model as its theoretical framework. Method: In-depth semistructured interviews were conducted with 11 older persons (mean age = 81 years) with ARHL. Results: Self-stigma was present in the lives of the participants. Analysis revealed the existence of 3 stages of self-stigma in which the 3 core dimensions of stigma (cognitive attributions: being old, stupid, and crippled; emotional reactions: shame, pity, and feeling ridiculed; and behavioral reactions: concealment, distancing, and adapting to hearing aids) were observed...
