Evaluation of Distortion and Transient Evoked Otoacoustic Emission in Tinnitus Patients with Normal Hearing
Introduction: Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of Distortion-Product Evoked Otoacoustic Emission (...

متن کاملDistortion product otoacoustic emission suppression tuning curves in normal-hearing and hearing-impaired human ears.
Distortion product otoacoustic emission (DPOAE) suppression measurements were made in 20 subjects with normal hearing and 21 subjects with mild-to-moderate hearing loss. The probe consisted of two primary tones (f2, f1), with f2 held constant at 4 kHz and f2/f1 = 1.22. Primary levels (L1, L2) were set according to the equation L1 = 0.4 L2 + 39 dB [Kummer et al., J. Acoust. Soc. Am. 103, 3431-34...
متن کاملDistortion product otoacoustic emission input/output functions in normal-hearing and hearing-impaired human ears.
DPOAE input/output (I/O) functions were measured at 7f2 frequencies (1 to 8 kHz; f2/f1 = 1.22) over a range of levels (-5 to 95 dB SPL) in normal-hearing and hearing-impaired human ears. L1-L2 was level dependent in order to produce the largest 2f1-f2 responses in normal ears. System distortion was determined by collecting DP data in six different acoustic cavities. These data were used to deri...
متن کاملOtoacoustic emission latency and hearing loss
Millions of people have the perception of sounds when no external sound is present: for many of them the“TINNITUS” (medical word from Latin) or “ACUFENE” (from Greek) is the trouble so severe to alter their quality of lifedeeply. Starting from 1998 we are carrying on with success an integral program of diagnosis, medical and rehabilitant treatment of the Tinnitus with a new multi therap...
