Distortion product otoacoustic emissions in tinnitus patients.
Tinnitus is a symptom that affects a great number of patients. Its diagnosis, treatment, and follow-up are difficult, owing to its subjectivity. The authors propose the use of distortion product otoacoustic emissions (DPOAEs) in tinnitus evaluation. They studied three groups: controls, having no complaint of tinnitus and normal hearing; group 1, presenting tinnitus and normal audiometry; and gr...
متن کامل[Characteristic of distortion product otoacoustic emissions for preterm newborn].
OBJECTIVE To investigate the characteristic of distortion product otoacoustic emissions (DPOAE) amplitude, SNR and noise in preterm newborns. METHOD DPAOEs at the 2f1-f2 frequency were recorded from 59 ears of 31 preterm newborns and 35 ears of 19 healthy fullterm newborns in response to equilevel primary tones at postnatal 3 days to 1 week. Detailed test included the recording of DPAOEs, SNR...

Phase characteristics and latency of 2f1-f2, 3f1-2f2, and 2f2-f1 acoustic distortion product otoacoustic emissions (DPOAEs) recorded in normally hearing adults have been described in a companion paper [Moulin and Kemp, "Multicomponent acoustic distortion product otoacoustic emission phase in humans. I. General characteristics," J. Acoust. Soc. Am. 100, 1617-1639 (1996)]. Phase-versus-frequency ...
متن کاملOtoacoustic emissions growth rate threshold: distortion product in neonates.
BACKGROUND Distortion product otoacoustic emission measures (DPOAE) verifies, among other characteristics, the emergence and growth rate of the DPOAE response according to sound stimulus intensity (growth curve). AIM To estimate the DPOAE threshold in neonates according to the DPOAE growth curve at 2 kHz and 4 kHz, with stimulus presentation ranging between 35 and 70 dB SPL. METHOD Particip...
