Study of the so-called cochlear mechanical tinnitus.
Stimulated oto-acoustic emission (OAE) was investigated in 225 ears with normal hearing and c5 dip hearing loss. Continual OAE persisting longer than 6 ms against the sound stimulation of relatively low intensities was frequently found in ears affected by tinnitus but without hearing loss and in the tinnitus ears with c5 dip hearing loss. The results suggest that there is an abnormality of cochlear micromechanics in these ears which might be related to the 'cochlear mechanical tinnitus' described by Kemp & Wilson in 1981.
