Abstract
Tinnitus retraining therapy has been heralded as a major advance in th e alleviation of tinnitus perception. A cornerstone of this technique is to use white noise produced by a white noise generator (WNG) over a period of several months in order to assist the patient to habituate to their tinnitus. There are three factors which influence the frequen cy spectrum of the perceived noise such that the perception of white n oise from a WNG is unlikely. These factors are the actual spectrum of the emitted noise, the ear canal resonance of the patient and the hear ing sensitivity of the patient. Advocates of tinnitus retraining thera py state that white noise is the optimal stimulation to assist habitua tion of tinnitus. This paper demonstrates that this optimal situation is unlikely to be achieved and that this may account for the long peri ods needed for patients to achieve benefit from the technique. The dev elopment of devices that allow for the above factors to be countered i s suggested.
