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)
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)
Two psychophysical methods, a method of adjustment (MOA) and a forced-choice double-staircase adaptive procedure (FCDS) (Jesteadt, 1980), were used to measure the predominant pitch and loudness of tinnitus for 11 subjects during one test session. The FCDS within-session variability of matches to tinnitus pitch was smaller than for the MOA and comparable to(More)
Spontaneous oto-acoustic emissions (SOAEs) were detected in 10 of 29 subjects with tinnitus. Because measures of the pitch of tinnitus are highly variable, the relation between the frequency composition of the tinnitus and the frequencies of SOAEs can not be known precisely. This raises the question of whether an observed SOAE could be proven to be the(More)

A series of experimental tests are presented indicating that numerous spontaneous otoacoustic emissions (SOAEs) are likely to provide the basis of monaural tinnitus for one female patient. For this patient, (1) the tinnitus disappeared only when all SOAE components were suppressed, (2) with all but one emission suppressed, the frequency of an external tone(More)
