Definitions

  • the invention relates to a tinnitus masking device with one or more signal generators, a controllable amplifier part 1 and one or two electroacoustic transducers for converting electrical into acoustic signals and with a voltage source.
  • Tinnitus stands for a wide range of symptoms that all 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 for some reason or is or is constantly excited and remains in this excitation state for a longer or shorter period. 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 on the 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 normally possible to identify a specific, often narrow or narrow frequency range within which the frequency of the tinnitus lies.
  • the object on which the invention is based 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 due to the avoiding auditory impression of one in the hearing frequency range notes or mixed sounds.
  • the invention is based on two findings:
  • the residual suppression is only recognized if the masking signal precisely matches the tinnitus signal in terms of frequency content.
  • the mask signal must be stronger.
  • the invention will now be explained in more detail on the basis of a circuit example which represents only the principle for the signal generator for the sinusoidal sound signal used in the invention with reference to the attached drawing.
  • 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.
  • 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 Tonsigna Igenerator 1 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 sound signal and is typically in the range from 0.1 to 0.2 Hertz.
  • the output signal of the oscillator 5 should not contain a DC component.
  • This output signal passes through a potentiometer 6 to a summing amplifier consisting of resistors 8a and 8b and an operational amplifier 9 to a second voltage-controlled oscillator 10.
  • the 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 electro-acoustic transducer 3 is connected to the output of the amplifier 1 3.
  • the potentiometer 6 is used for setting the tone frequency range swept by the audio frequency generator, and the potentiometer 7 is used for input Position of the center frequency of the swept audio frequency range.
  • the potentiometer 6 is set so that the output voltage of the oscillator 5 is completely damped. Then the potentiometer 7 in conjunction with an external frequency counter connected to the terminal 11 for determining an upper and a lower limit frequency for the tinnitus of the patient, i.e. the audible tone. Then the potentiometer 7 is set so that the output frequency of the oscillator 10 lies in the middle between the upper and lower limit frequency.
  • a sound signal is slowly generated which continuously sweeps over the range between the lower and the upper limit frequency.
  • the repetition frequency can be adjusted with the potentiometer 4.
  • the patient can then adjust the volume himself using the potentiometer 12.
  • the patient can also switch the replacement 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 is preferred should only be used under instruction, better still under the supervision of an experienced hearing aid acoustician, or even better a doctor in an ENT clinic.
  • the invention thus created a new type of tinnitus masking device with which a tinnitus consisting of a pure tone can be suppressed temporarily or permanently with great probability of success.

Abstract

La présente invention se rapporte à un dispositif de masquage du tintement d'oreilles comportant un ou plusieurs générateurs de signaux, un amplificateur réglable (2) et un ou deux transducteurs électroacoustiques (3) pour la conversion de signaux électriques en signaux acoustiques, ainsi qu'une source de tension. Dans ce dispositif, au moins un des générateurs de signaux (1) engendre un signal sonore sinusoïdal pur se répétant en continu et balayant lentement la gamme des fréquences acoustiques, dont la durée de cycle est réglable entre 0,1 et 1000 s.
