Patent ID: 8144908

Claim:
A method for damping a resonance frequency in a vibrator for a bone conduction hearing aid in which sound information is mechanically transmitted via a skull bone to an inner ear of a person with impaired hearing and in which the bone conduction hearing aid comprises a microphone to pick up the sound information, a signal processor adapted to process an electrical signal from the microphone and a vibrator to convert the electrical signal into vibrations to be conducted to the skull, the method comprising: utilizing the signal processor of the hearing aid for damping a resonance frequency peak of the vibrator by: reducing an amplification of a first range of frequencies of the electrical signal encompassing at least a frequency corresponding to the resonance frequency of the vibrator; maintaining an amplification of a second range of frequencies of the electrical signal, wherein the second range of frequencies is a range of frequencies lower than those of the first range of frequencies; and maintaining the amplification of a third range of frequencies of the electrical signal, wherein the third range of frequencies is a range of frequencies higher than those of the first range of frequencies.
