[Acoustic distortion products. Recordings from patients with normal hearing and those with sensorineural hearing loss].

Distortion product otoacoustic emissions (DPEs) are a subtype of evoked otoacoustic emissions that represent a class of cochlear response. Because of their frequency specificity and the wide range of frequencies explored DPEs have a great potential for clinical use. DPEs studies include DP-audiograms and input/output functions. We recorded 27 DPEs, 24 of them from normal ears and 3 from pathological ears. This report resumes methods and results.
