The Effects Of Age On The Perception Of Frequency In Noise, Mary E. Scherer
The Effects Of Age On The Perception Of Frequency In Noise, Mary E. Scherer
Dissertations, 2014-2019
Difficulty understanding speech in the presence of background noise is one of the most common complaints of older adults, both with and without hearing loss. One possible contributing factor is an age-related decline in neural synchrony (e.g., phase locking). Tones-in-noise were used in an attempt to disrupt rate-place coding of frequency and to encourage participants to use phase-locked, temporal representations of frequency during a behavioral frequency discrimination task. Fourteen adults participated in the study (five younger, aged 21-29; four middle aged, 41-50; and five older, aged 61-80). Participants had clinically normal hearing sensitivity (≤ 25 dB HL at octave frequencies …

Development of a Deployable Stereo-Hearing System
ABSTRACT
Objective: To investigate the effectiveness and efficiency of a portable stereo-hearing testing system with the intent of deployment for data collection in future studies. We quantify sound localization accuracy and speech-in-noise thresholds comparing unilateral (such as single-sided deafness) and bilateral subjects. We desired to design a small, inexpensive system that would show a large effect size between binaural and monaural subjects in a variety of stereo hearing tasks.
Methods: Subjects were tested on localization accuracy and speech understanding in noise using a laboratory-made stereo-hearing testing device. For the …
