Distortion Product Otoacoustic Emissions: Hit And False-positive Rates In Normal-hearing And Hearing-impaired Subjects

Abstract

DPOAEs have acceptable hit and false-positive rates for high frequencies but not for lower frequencies. DPOAE amplitude-to-noise ratios of +3 and even +6 dB may not be clinically feasible based on the current data. The overall findings obtained on the commercial instrument in this study compare favorably with previous studies of a similar nature.
