The goal of this project is to design an electronic earpiece that can provide a robust way to monitor users’ hearing capabilities over time, as well as to automatically compensate for mild hearing loss through multi-band amplification, dynamic compression and equalization of audio playback. Currently, CRITIAS has experience in designing electroacoustic earpieces with calibrated microphone and receivers [1], and has further developed methods for precise measurement of in-ear levels [2-3]. The student will work on the development of audio equalization filters as well as multi-band dynamic compressors for increased speech intelligibility for users with mild hearing losses in low ambient noise conditions.
