Hearing aids and cochlear implants are two major hearing en- hancement technologies but yet share little in research and development. The purpose of this study was to determine whether hearing aid directional micro- phones and noise reduction technologies could enhance cochlear implant us- ers' speech understanding and ease of listening. Digital hearing aids serving as preprocessors were programmed to omni-directional microphone, direc- tional microphone, and directional microphone plus noise reduction condi- tions. Three groups of subjects were tested with the hearing aid processed speech stimuli. Results indicated that hearing aids with directional micro- phones and noise reduction algorithms significantly enhanced speech under- standing and listening comfort. © 2004 Acoustical Society of America
