The design and evaluation of a hearing aid with trainable amplification parameters

Abstract

OBJECTIVES: A prototype hearing aid with trainable amplification parameters (compression threshold, gain below the compression threshold, compression ratio, and noise suppression strength) was evaluated to answer the following research questions: (1) In everyday listening situations, do aid users prefer amplification parameters that were a result of training the aid in such situations to a set of untrained parameters that were prescribed and customized in a clinic? (2) Does the provision of trained noise suppression significantly increase the preference for the trained settings? (3) Is the preference for the trained settings correlated with a measure of training? DESIGN: Three take-home tria..
