Distortion-product otoacoustic emissions (DPOAEs) are generated in the cochlea in response to two tones of a given frequency and sound pressure level presented in the ear canal. DPOAEs are an objective indicator of normally functioning cochlea outer hair cells.
Our HearID and OtoStat systems employ computer-generated stimuli, automated data monitoring, and advanced signal processing for noise and artifact rejection. Data are collected rapidly and conveniently. Our DPOAE systems were developed using the same digital signal processing (DSP) and DPOAE measurement algorithms and the same hardware principles as the original CUBeDIS™ DPOAE Measurement System, developed at AT&T Bell Labs as a research tool. Through the dedication of engineers and scientists at Ariel, Etymōtic, universities, and research centers, it has developed into a widely-used clinical measurement system.
For use with newborns, infants, children, and adults.
