Tinnitus retraining therapy has been heralded as a major advance in the 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 frequency spectrum of the perceived noise such that the perception of white noise from a WNG is unlikely. These factors are the actual spectrum of the emitted noise, the ear canal resonance of the patient and the hearing sensitivity of the patient. Advocates of tinnitus retraining therapy state that white noise is the optimal stimulation to assist habituation of tinnitus. This paper demonstrates that this optimal situation is unlikely to be achieved and that this may account for the long periods needed for patients to achieve benefit from the technique. The development of devices that allow for the above factors to be countered is suggested.
耳鸣再训练疗法被誉为缓解耳鸣感知方面的一项重大进展。该技术的一个基石是在几个月的时间里使用白噪声发生器（WNG）产生的白噪声，以帮助患者适应其耳鸣。有三个因素会影响所感知噪声的频谱，使得从WNG感知到白噪声不太可能。这些因素是所发射噪声的实际频谱、患者的耳道共振以及患者的听力敏感度。耳鸣再训练疗法的支持者称白噪声是帮助耳鸣适应的最佳刺激。本文表明这种最佳情况不太可能实现，这可能解释了患者从该技术中获得益处所需的较长时间。建议开发能够抵消上述因素的设备。
