Summary

The discovery of the presence of spontaneous mechanical activity within the cochlea has lead to speculation that this may be responsible for some forms of cochlear tinnitus. However, attempts in the present study, and also in other studies from the literature, to show a relationship between the measured spontaneous acoustical emissions in the external meatus and the subjective pitch matching of tonal tinnitus have not been very successful. In only two tinnitus patients out of 53 could an acoustic emission be detected which appeared to correlate with the subjective complaint.

A simple apparatus for the detection of acoustical emissions is described and the possible mechanisms for the generation of cochlear tinnitus are discussed.
