Effect of age on directional microphone hearing aid benefit and preference.

abstract：BACKGROUND:A deficit in the processing of auditory information may underlie problems in understanding speech in the presence of background noise, degraded speech, and in following spoken instructions. Children with auditory processing disorders are challenged in the classroom because of ambient noise levels and maybe a...
