Abstract

The ability of normal hearing linteners to differentiate the sound quality of different Bone-Anchored Hearing Aids's (BAHA) different processing condition was investigated. For the study, two objective measures of sound quality were obtained form the input and output BAHA recordings using MATLAB. A predictable advantage was found for the Compact with output compression as the input speech level increased. However, for the Compact, a consequence of output compression is reduced MPO.
