Article Synopsis
- The study investigates how hearing aid processing delays affect the perception of voiced and voiceless consonants (/d/ vs. /t/) in older adults with hearing loss, focusing on how these delays can distort important temporal cues.
- Nineteen participants with mild-moderate sensorineural hearing loss performed a categorization task using sounds modified to simulate different processing delays (0, 0.5, 5, and 8 ms) while their responses were analyzed statistically.
- Results showed that longer processing delays shifted the perception towards voiced sounds and caused a noticeable change in how easily listeners could distinguish between the two consonants, highlighting the importance of timing in effective hearing aid design.
Objectives: Traditionally, early repolarisation (ER) is considered a benign ECG variant, predominantly found in youths and athletes. However, a limited number of studies have reported an association between ER and the incidental occurrence of ventricular fibrillation or sudden cardiac death. Yet definite, direct comparisons of the incidence of ER in unselected, contemporary populations in athletes as compared with non-athletes and across different sports are lacking.

However, an MPO that is too low, as in the cases to avoid discomfort for people with a severe loudness tolerance problem and hearing losses that exceed the fitting range of the hearing aids, could negatively affect sound quality and speech intelligibility in noise.
Purpose: The current study was designed to demonstrate the degradation in speech intelligibility in noise on the HINT (Hearing in Noise Test) when the MPO of the wearers' hearing aids was lowered by 10 dB from the default.
Objectives: Many new processing features in hearing aids have their primary effects on information located in the high frequencies. Speech perception tests that are optimized for evaluating high-frequency processing are needed to adequately study its effects on speech identification. The goal of the current research was to develop a medium for evaluating the effects of high-frequency processing in hearing aids.

Research Design: Comparison of results on the Hearing in Noise Test (HINT) and the Acceptable Noise Level task (ANL).
Study Sample: Eighteen participants with varying configurations of sensorineural hearing loss.
