If the detected value lies outside a predetermined range comprising the reference value, it may be signalled to the operator of the hearing aid that the hearing aid comprises a defect.
  • the type of defect may also be signalled. For example, a specific tone or a specific sequence of tones may be generated by the output transducer signalling that the hearing aid is defect to the hearing impaired user. A specific tone or a specific sequence of tones may correspond to a specific defect.
  • the hearing aid is connected to a hearing aid programming device with a display, the fact that the hearing aid comprises a defect may be displayed on the display and, further, an indication of the type of defect may be displayed.

  • the type of defect may also be signalled. For example, it may be displayed on the display of a programming device that the input port to the input transducer in question should be checked for ear wax.
  • the input transducer connected to the signal path may be the pick-up coil.

  • the compression of the signal processor i.e. gain as a function of input level may be determined, e.g. as a function of frequency.
  • an adaptive feedback loop comprising an adaptive filter in the hearing aid to compensate for acoustic feedback.
  • Acoustic feedback occurs when the input transducer of a hearing aid receives and detects the acoustic output signal generated by the output transducer. Amplification of the detected signal may lead to generation of a stronger acoustic output signal and eventually the hearing aid may oscillate.
  • the adaptive filter estimates the transfer function from output to input of the hearing aid including the acoustic propagation path from the output transducer to the input transducer.
  • the input of the adaptive filter is connected to the output of the hearing aid and the output signal of the adaptive filter is subtracted from the input transducer signal to compensate for the acoustic feedback.
  • a hearing aid of this type is disclosed in US 5,402,496.
  • the test controller may be adapted to verify operation of the adaptive feedback loop, e.g. the test controller may control a signal switch to disconnect the feedback loop from the signal path and increase the gain of the signal processor until oscillation occurs.
  • the hearing aid is situated in the compartment with hard walls during this test.
  • the test controller may further be adapted to reconnect the adaptive feedback loop to the signal path whereby oscillation should seize if the adaptive feedback loop operates correctly.
  • the hearing aid may comprise a test signal generator for injection of a digital signal at a selected second point in the digital part of the signal path of the hearing aid, e.g. at the input of the signal processor.

  • the parameters may relate to frequency, amplitude, spectrum, modulation, phase, etc, and the parameter values of a hearing aid operating without defects are desired values.
  • the test controller may further be adapted to compare the parameter values of the actual response signal with the desired values to determine whether the hearing aid comprises a defect. If an actual value lies outside a predetermined range comprising the respective desired value, it may be concluded that the hearing aid in question comprises a defect. The presence of a defect may be signalled to the operator of the hearing aid as previously described.
  • the self-test may be initiated upon user activation of at least one switch positioned on the hearing aid housing, or on a hearing aid programming device, or on a remote control unit for the hearing aid, or on a fitting system, etc.
  • Preferably two switches has to be activated simultaneously or sequentially to avoid accidental activation of the self-test.

  • the input transducer connected to the signal path may be the pick-up coil 16.
