A matching-to-sample feedback technique for training self-control of tinnitus.
Thirty individuals with subjective tinnitus aurium of a variety of types and severity were treated with a matching-to-sample feedback procedure. Following initial evaluation measures, the participants' experienced tinnitus sounds were reproduced audiometrically on all characteristics and were presented to them in the noninvolved ear or in both ears when the tinnitus was binaural. This experimental sound was then reduced in 5 decibel (dB) steps within sessions, and participants had the task of concentrating on reducing the loudness of their tinnitus until a match was achieved between it and the experimental sound at each new dB level. Results showed an overall highly significant difference in dB levels from baseline to final training session. Nearly all participants demonstrated a marked reduction in tinnitus loudness, with 84% reducing it by 10 dB to 62 dB and several eliminating it completely. Individual and pathological variables played no role in training or outcome. Our approach appears to have major advantages over other tinnitus treatment strategies in that it provides direct, significant relief and gives the patient the psychological benefit of gaining control over the problem.
