Further efforts to predict pure-tone thresholds from distortion product otoacoustic emission input/output functions.
Recently, Boege and Janssen [J. Acoust. Soc. Am. 111, 1810-1818 (2002)] fit linear equations to distortion product otoacoustic emission (DPOAE) input/output (UO) functions after the DPOAE level (in dB SPL) was converted into pressure (in microPa). Significant correlations were observed between these DPOAE thresholds and audiometric thresholds. The present study extends their work by (1) evaluat...
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 ...
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 کاملAlteration of distortion product otoacoustic emission input/output functions in subjects with a previous history of middle ear dysfunction
BACKGROUND The aim of this study was to investigate the effects of sub-clinical alterations on the amplitudes and slopes of the DPOAE input-output responses from subjects with previous history of middle ear dysfunction. MATERIAL/METHODS The study included 15 subjects with and 15 subjects without a history of otitis media in the last 10 years. All participants were assessed with acoustic immit...
متن کاملInput-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...
