The tinnitus retraining therapy(TRT) is an effective method for treating tinnitus patients. This therapy use the white noise to stimulate auditory cells for a wide frequency range. In this paper, the small white noise generator using the thermal noise is proposed. And frequency response controller which can compensate the frequency response changed by the human outer and middle ear system is proposed. We can know that proposed system is more proper type on a purpose of the tinnitus retraining therapy comparing with conventional white noise generator.

Background and Objectives Tinnitus retraining therapy (TRT) is one of the most effective treatment modalities of tinnitus based on the neurophysiological model proposed by Jastreboff and Hazell. This study was performed to evaluate the effect of counselor factor on treatment outcomes of TRT. Subjects and Method The total of 78 patients who had TRT from three different counselors in a tinnitus clinic of tertiary referral center from Jan 2015 to Dec 2015 were included in this study. Their medical records were retrospectively reviewed to evaluate the therapeutic response to TRT. Results Among 78 patients who were followed-up for more than 6 months, 47, 20, and 11 patients were treated by counselors A, B, C (all ENT specialists), respectively. Counselor A had 15-year-experience of TRT counseling, whereas counselor B and C were well trained but beginners of TRT counseling. Initial clinical characteristics including Tinnitus Handicap Inventory (THI) and tinnitus Visual Analogue Scale (VAS) scores of the patients among three groups were not significantly different. Treatment responses evaluated via THI and most of the tinnitus VAS scores after at least 6 months after TRT were significantly improved in all three groups (p<0.05) with no significant difference between the senior (A) and junior (B, C) group. Conclusion TRT seems to be an effective treatment modality of tinnitus even in this short term follow-up study. Treatment outcomes of TRT may not depend on the counselors once they are well trained and follow the same protocol.

The tinnitus which is the one of the auditory disease is a phenomenon that the patients feel the sound in the ear or the head when there is no sound sources. There have been many therapies for this tinnitus so far, but it is known that the TRT (Tinnitus Retraining Therapy) is the most effective therapy. So we designed and developed the controllable white noise generator for TRT. It must be designed as small as possible for user's convenience, such as the ITE (In The Ear) type hearing aids. It used the thermal noise as the white noise source. And filter and tone control circuits are used at the end of the noise generation part to control the white noise characteristics. This link of the controllable circuits is used to change the white noise's characteristic for the various tinnitus patients' characteristic. we can confirm that the designed and implemented controllable white noise generator which is a ITE type operates properly by the experiments of filter and tone control circuit.
