Definitions

  • the invention relates to a tinnitus masking device for the treatment of tinnitus with one or more signal generators, a controllable amplifier part and one or two electroacoustic transducers for converting electrical into acoustic signals, and with a voltage source.
  • DE-U1-8 815 877 a tinnitus masking device with an electronic circuit for generating a sound spectrum that masks the tinnitus.
  • This spectrum contains a line spectrum with at least one discrete tone frequency.
  • the user of the device can set both the sound intensity and the frequency of the tone generator and, if necessary, also switch on a noise signal. In any case, the signal generated in this way must be louder than the tinnitus so that it is masked.
  • Tinnitus stands for a wide range of symptoms, all of which have to do with hearing function, in particular with the middle ear, the organ of the corti, the nerve cells and the nerve strands and the nerve centers that lead from the organ of the corti to the brain.
  • the reason why the patient believes that he is hearing a tone of a certain frequency is evidently to be seen in the fact that the nerve that would normally transmit a really audible tone of this frequency to the brain is sporadic or for some reason is or is constantly excited and remains in this excitation state for longer or shorter periods. This could be caused, for example, by an electromechanical disturbance or such a "misfire" in this nerve cell or in a previous nerve cell.
  • a tinnitus masking device is an instrument worn on the head or on the body and head, for example in the manner of a hearing aid, which generates a type of acoustic signal, e.g. a sinusoidal sound, narrowband noise, broadband noise or white noise, which is either transmitted to the patient via headphones or via a miniature receiver which is built into a hearing aid housing.
  • a type of acoustic signal e.g. a sinusoidal sound, narrowband noise, broadband noise or white noise
  • This can be a BTE device, for example.
  • a standard hearing aid has been found useful because the hearing aid raises the overall background noise level, allowing the patient to distinguish it from his tinnitus.
  • the present invention relates only to such tinnitus which is perceived as a tone. In these cases it is usually possible to identify a specific, often narrow or narrow frequency range within which the frequency of the tinnitus lies.
  • a tone generator repeats this frequency range slowly and slowly, then the true tinnitus frequency may be expected to be actually and repeatedly hit, although the patient does not know exactly when this is the case.
  • the object underlying the invention be is therefore to create a tinnitus masking device of the type mentioned at the outset, which, on the basis of tests carried out, appears to be particularly suitable for the treatment of the special tinnitus mentioned above, which is noticeable by the audible impression of a tone or sound mixture lying in the hearing frequency range.
  • the tinnitus masking device according to the invention is to be installed, for example, in a hearing device, such as a BTE device, which contains one or more signal generators, a controllable amplifier and at least one electromechanical converter and a voltage source.
  • a hearing device such as a BTE device, which contains one or more signal generators, a controllable amplifier and at least one electromechanical converter and a voltage source.
  • the signal generator 1 generates a continuously repeating, sinusoidal, pure sound signal that slowly sweeps over the hearing frequency range and is supplied to an electroacoustic transducer 3 via a controllable amplifier 2.
  • the tone signal generator 1 basically consists of a voltage-controlled oscillator 5 that can be controlled via the variable output voltage of a potentiometer 4. the frequency of the signal generated by the oscillator 5 is controlled with the voltage tapped at the potentiometer 4. This signal determines the repetition frequency of the audio signal and is typically in the range from 0.1 to 0.2 Hertz.
  • the output signal of the oscillator 5 should not contain any DC component.
  • This output signal is sent via a potentiometer to a sum amplifier consisting of resistors 8a and 8b and an operational amplifier 9 to a second voltage-controlled oscillator 10. Sum amplifier 8a, 8b, 9 is also fed by the output voltage of a further potentiometer 7.
  • the output signal of the oscillator 10 arrives once at the output amplifier 2, which here, in a highly simplified manner, consists of a potentiometer 12 and an amplifier 13, and also at a connection 11 for a frequency counter.
  • the electroacoustic transducer 3 is connected to the output of the amplifier 13.
  • the potentiometer 6 is used to set the tone frequency range swept by the tone frequency generator, and the potentiometer 7 is used to adjust the center frequency of the swept tone frequency range.
  • the patient can also switch the noise generator of the device, if present, on or off.
  • the repetition frequency is low enough. If the repetition frequency is too high, e.g. higher than about 10 to 20 Hz, then the sound signal is no longer perceived as a sound but as a much more complex signal to which the patient can no longer assign his tinnitus. It is much more important that tinnitus and sound signal are perceived as equivalent.
  • this tinnitus masking device should preferably only be used under the guidance, better still under the supervision of an experienced hearing aid acoustician, even better a doctor in an ENT clinic.
  • the invention thus created a novel tinnitus masking device with which a tinnitus consisting of a pure tone can be suppressed temporarily or permanently with a high probability of success.
