STUDY OF TINNITUS INDUCED TEMPORARILY TO NOISE

Subjects were exposed in one ear for 5 min to 13 oct band noise centered at either 2, 3, 4, or 6 kHz at 110 dB SPL. The resulting aftersensation, called “noise induced short duration tinnitus” (NIST) was matched for pitch and loudness in the nonstimulated ear. It was found that the pitch of NIST bears a constant relation to the frequency of the stimulus and that the difference between the equivalent frequency of NIST and the frequency of maximum threshold shift was equivalent to one critical band. © 1968, Acoustical Society of America.
