Definitions

  • the present invention relates to a method of adapting a hearing aid having a multi-channel processing unit to a hearing aid wearer by setting each individual processing value for each channel of the processing unit to a respective default value that is individual to the hearing aid wearer.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided.
  • BTE behind-the-ear hearing aids
  • ITO in-the-ear hearing aids
  • CIC canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 also in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • the sound of a hearing device or hearing system is essentially characterized by the frequency-dependent amplification.
  • this is realized in any number of channels on the basis of calculated target gain curves by different levels of attenuation of individual channels.
  • the setting of these channels takes into account the individual electroacoustics. In this case, for example, resonances of a hearing system are compensated.
  • the result of the basic setting is thus a pre-calculated frequency response of the hearing system, which is composed of different settings of the channel filter bank and the individual electroacoustics.
  • the default setting is usually just a starting point for hearing aid fitting, and subsequently the adaptive audiologist is required to shape the frequency response based on his client's needs. For this he has access to the filter bank and can adjust the attenuation of the individual channels.
  • FIG. 2 a typical result of a channel damping after the default setting for a 16-channel device is shown.
  • the figure shows an equalizer setting over 16 channels, which are arranged side by side with increasing frequency.
  • the set value for each channel k1, k2, ..., k16 is optically symbolized by an actuating element b1, b2,..., b16 as in the case of an equalizer.
  • the position of each actuating element b1, b2,..., B16 thus represents the set filter or damping value for the respective channel k1, k2,..., K16.
  • the rectangles b1, b2,..., B16 do not represent physical actuators but, for example, only graphical symbols that can be drawn with a computer mouse or only the represent each set value of the channel.
  • match modules provide the ability to display the set levels in each channel, but this does not support further intuitive customization.
  • the object of the present invention is therefore to improve the fine adjustment of hearing aids by intuitively acting aids.
  • this object is achieved by a method for adapting a hearing device that has a multi-channel processing unit to a hearing aid wearer by setting an individual processing value for each channel of the processing unit to a respective basic adjustment value that is individual for the hearing aid wearer each of the processing values to the respective default setting value and further adjusting the processing values to the hearing aid wearer relative to the normalized processing values.
  • the processing unit is a filter bank and the processing values are filter values.
  • the processing values are filter values.
  • the advantage according to the invention can also be used, for example, for an amplifier unit as a processing unit.
  • Relative fitting can be done using a drop-down menu that selects one of several predetermined relative fitting combinations, which are relative fitting values for all channels.
  • a relative increase in the fitting values may occur in only those channels that represent a mid-range of acoustically observable frequencies. In this way, z. B. voice signals over other sounds amplified play.
  • the previous absolute representation of the channel level is according to the invention accordingly FIG. 2 in a relative representation according to FIG. 3 transformed.
  • the set value of each channel k1 to k16 to the value of the respective default setting, in this case the in FIG. 2 displayed value normalized.
  • the actuators b1 to b16 automatically on a baseline G, z. B. a 0-line aligned. Such normalization can take place at arbitrary times.
  • the graphic of FIG. 3 which represents the actuators b1 to b16 and the corresponding channel adjustment values of the filter bank, thus becomes a basis for a relative representation with respect to a basic setting or a "FirstFit".
  • the user can also carry out a corresponding basic setting himself at any later time and use it for normalization.
  • the upper limit L, z As the maximum gain, in the graph of FIG. 3 to be displayed. This is particularly helpful for recognizing which dynamic range is available in the respective channel.
  • FIG. 4 illustrated set value combination for the individual channels k1 to k16.
  • the seven highest frequency channels were raised slightly.
  • the highest frequencies thereof are raised more than the lower of the high frequencies, so that results in an approximately linear increase to the highest frequencies out.
  • the actuating elements b1 to b16 thus represent a specific adaptation or setting value combination, which is graphically reflected in a so-called "shape".
  • the "shape" of FIG. 4 serves to lift the heights. For example, different "shapes" can be determined for different listening situations.
  • FIG. 5 For this purpose, another concrete example is given, which reproduces a "shape" for lifting the centers.
  • FIG. 6 an example in which the depths are lowered. This is also easy to recognize from the normalized representation.
  • the lowest frequency channels are attenuated from the default setting. The attenuation increases with decreasing frequency.
