The influence of training on tinnitus perception: an evaluation 12 months after tinnitus management training

Sixty-five subjects were reviewed 12 months after tinnitus management training, which had been comprised variously of information, relaxation training and a therapeutic noise strategy. Seventy-four per cent of subjects reported increased habituation to tinnitus (n = 48), 65% reported reduced tinnitus annoyance (n = 42), and 52% reported an increased ability to cope with tinnitus (n = 34). Twenty-five per cent of subjects: reported deterioration in coping ability (n = 16), 23% reported reduced habituation to tinnitus (n = 15) and 8% reported increased tinnitus-related annoyance (n = 5). None of the management strategies were found to be significantly more effective than others in facilitating improved coping or habituation to tinnitus. Subjects who reported reduced coping and habituation to tinnitus experienced greater levels of general life stress than subjects who reported increased habituation and coping ability. The use of relaxation therapies as applied in this study did not appear to influence the level of tinnitus distress or the level of life stress. Thirty-seven per cent of subjects given long-term low-level white noise (LTWN) stimulation reported benefit, However, LTWN stimulation did not significantly alter tinnitus awareness or the minimum masking level (MML) of tinnitus. Long-term low-level white noise stimulation appeared to influence cognitive reaction to tinnitus rather than its physical perception. Subjects who initially had low ability to cope with tinnitus and preferred a more active coping style reported significantly greater benefit from LTWN stimulation than subjects whose primary approach to coping was to regulate the emotional impact of tinnitus.
