  • Active noise suppression for a hearing aid device which can be worn in the ear or a hearing aid device with otoplastic which can be worn in the ear
    Patent number: 6920227
    Abstract: In the case of a hearing aid device which can be worn in the ear or a hearing aid device with a otoplastic which can be worn in the ear, the penetration of direct sound through a ventilation channel of the hearing aid device or of the otoplastic is prevented. An acoustic signal is picked up from the ventilation channel via a second microphone in a first region of the ventilation channel and phase-shifting it in a filter device in such a way that the direct sound is at least largely eliminated after the phase-shifted signal is emitted into the ventilation channel via a second earphone. The invention offers the advantage that an enlargement of the cross section of the ventilation channel is made possible as a result, even to provide an open supply, without disturbing direct sound getting into the auditory canal of the person wearing the hearing device.
