Abstract

A simple structure that compensates for frequency-dependent loudness recruitment of sensorineural hearing loss is presented. The non-linear structure estimates total input signal energy, and then weights and combines the output of two parallel filters based on this energy estimation. Preliminary evaluation of this structure with noise-masked normal hearing listeners, and speech recorded in naturally noisy environments, shows a 15-20% performance increase in word recognition scores when compared to a linear structure
