The invention relates to a device for determining the frequency of at least one dominant tone of a tinnitus perceived by a patient, comprising a tone generator for playing tones, an input unit for patient entry of evaluations about the tones played, and a control and analysis unit coupled to the tone generator and the input unit and designed to carry out a similarity measurement and a comparison of pairs of tones, wherein the control and analysis unit controls the tone generator for the similarity measurement in such a way that same plays successive tones, and, after playing a respective tone, the control and analysis unit receives the patient's evaluation entered into the input unit with respect to the similarity of the tone to the at least one dominant tone of the tinnitus. The control and analysis unit controls the tone generator for the comparison of pairs of tones in such a way that it plays successive pairs of tones, and, after playing a respective pair, the control and analysis unit receives the patient's evaluation entered into the input unit as to which tone of the pair is more similar to the at least one dominant tone of the tinnitus, and the control and analysis unit combines the results of the similarity measurement and the comparison of pairs of tones and determines from this at least one tone, the frequency of which is most similar to the frequency of the at least one dominant tone of the tinnitus. |
