Interactions Between Digital Noise Reduction and Reverberation: Acoustic and Behavioral Effects.

ABSTRACT:

Background

Digital noise reduction (DNR) processing is used in hearing aids to enhance perception in noise by classifying and suppressing the noise acoustics. However, the efficacy of DNR processing is not known under reverberant conditions where the speech-in-noise acoustics are further degraded by reverberation.

Purpose

The purpose of this study was to investigate acoustic and perceptual effects of DNR processing across a range of reverberant conditions for individuals with hearing impairment.

Research design

This study used an experimental design to investigate the effects of varying reverberation on speech-in-noise processed with DNR.

Study sample

Twenty-six listeners with mild-to-moderate sensorineural hearing impairment participated in the study.
