For patients with noise-induced sensorineural hearing loss, the results of matching a binaurally presented comparison tone to subjective tinnitus during a 20-day test period are reported. As a control, results of matching an external comparison tone to a standard tone are also presented. The variability for tinnitus measurements was extremely large relative(More)

In general, the detectability of a signal preceded and followed by noise maskers is less than the prediction based on a simple addition of the effects of the maskers (i.e., an intensity sum). Data verifying and extending this finding were collected in a variety of conditions in which the two maskers either surrounded the signal in time or preceded it. These(More)
Prototypical experimental tests for linking spontaneous otoacoustic emissions with disruptive tinnitus have been described previously. Using similar experimental tests on 96 tinnitus sufferers, an estimate is made here of the prevalence of tinnitus caused by spontaneous otoacoustic emissions: the 95% confidence limits of this estimate are 1.11% and 9.05%.
Ten patients with sensorineural hearing loss and tinnitus matched external tones to the tinnitus pitch. These matches were followed by magnitude estimates to measure the loudness function of tones at 1 kHz at the presumed tinnitus frequency (i.e., at the average frequency matching the pitch of the tinnitus), magnitude estimates of the tinnitus itself, and(More)
The potential influence of spectral analysis factors on estimates of the prevalence of spontaneous otoacoustic emissions (SOAE) was explored. The detection of a SOAE was influenced by two spectral factors: (1) the frequency resolution of the spectrum, and (2) the number of spectral averages. For 15 different combinations of these two factors, the estimate(More)
Sounds from the ear canal were measured and then analyzed off-line. A peak-picking algorithm located spectral maxima which might be designated as spontaneous otoacoustic emissions (SOAEs). The output from a 0.5-cc syringe, used to stimulate the volume of the ear canal, was also measured, analyzed and used to approximate the false-alarm rate of the(More)
For 7 patients with sensorineural hearing loss and tinnitus, pitch and loudness matches were made to the tinnitus. These matches were followed by measurement of three psychometric functions (probability of a correct response as a function of signal level) for pure tones, one in the presumed tinnitus region (i.e., at the average frequency matching the pitch(More)
OBJECTIVE The frequencies of one subject's spontaneous otoacoustic emissions (SOAEs) were tracked intermittently for 295 days. DESIGN The first 40 days encompassed a normal menstrual cycle. During the next 186 days, the subject exhibited amenorrhea. For the last 69 days, she took oral contraceptives prescribed by her doctor to reestablish menstrual(More)
