Input-output functions of the nonlinear-distortion component of distortion-product otoacoustic emissions in normal and hearing-impaired human earsa)
Distortion-product otoacoustic emissions (DPOAEs) arise in the cochlea in response to two tones with frequencies f1 and f2 and mainly consist of two components, a nonlinear-distortion and a coherent-reflection component. Wave interference between these components limits the accuracy of DPOAEs when evaluating the function of the cochlea with conventional continuous stimulus tones. Here, DPOAE co...
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 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 کاملOtoacoustic emissions from normal-hearing and hearing-impaired subjects: distortion product responses.
Distortion product otoacoustic emissions (DPOAE) were measured in normal-hearing and hearing-impaired human subjects. Analyses based on decision theory were used to evaluate DPOAE test performance. Specifically, relative operating characteristic (ROC) curves were constructed and the areas under these curves were used to estimate the extent to which normal and impaired ears could be correctly id...
متن کاملDistortion-product otoacoustic emission input/output functions as a function of frequency in human adults.
Two issues concerning distortion-product otoacoustic emission (DPE) input/output functions were addressed in the present study. The first was to characterize those functions from threshold to 65 dB SPL. The second concerned the extent to which DPE input/output functions vary as a function of frequency. DPE input/output functions were generated at 20 frequencies from 537 to 10,009 Hz from eight ...
