Speech perception in children using advanced acoustic signal processing

New acoustic processing strategies have been developed to improve the speech perception of listeners with sensory hearing loss. These strategies currently include digital signal processing, variable compression, multiple memories, noise-reduction algorithms, directional-microphone technology, and automatic program selection—all features designed to improve the performance and versatility of hearing instruments. Devices that incorporate such advanced acoustic signal processing (AASP) technologies are being recommended for infants and children, although few empiric data are available that demonstrate increased benefit over well-fitted analog devices incorporating wide dynamic range compression circuitry1 for use with the pediatric population. The purpose of our study was to examine the speech-perception abilities of eight children with sensory hearing loss using their own hearing instruments and AASP technology, specifically the Phonak Claro.
