Abstract:
Wide dynamic range compression (WDRC) and noise reduction (NR) algorithms are common hearing aid technologies in digital hearing aids, and since these are nonlinear algorithms, they may cause the output signal-to-noise ratio (SNR) to be different from the input SNR for hearing aids. The current study aims to investigate the effects of temporal features of background noise (i.e., the number of background talkers) and amplification prescriptions, based on audiometric configurations, on SNR at the output of the hearing aid. This is the first study to investigate these effects with a commercial hearing aid with both WDRC and NR algorithms.
