Abstract
An acoustic module for a hearing aid device has at least one microphone and at least one earphone (acoustic output transducer) combined together as a unit, the unit including a signal-processing unit for feedback suppression that is connected with the microphone and the earphone. Feedback signal portions are removed from the microphone signal by the signal-processing unit. The acoustic module places acousto-mechanical components within a unitary component, with acousto-mechanical characteristics that can be measured and included in the signal processing for feedback suppression.
Claims31
An acoustic module for a hearing aid device comprising a unit adapted for insertion in the hearing aid device comprising an acousto-electrical transducer and an electro-acoustical transducer, said acousto-electrical transducer and said electro-acoustical transducer having feedback associated therewith, and said unit further comprising a signal-processing unit for suppressing said feedback.
A hearing aid device comprising:
- a unit comprising an acousto-electrical transducer and an electro-acoustical transducer and a signal processor for suppressing feedback associated with said acousto-electrical transducer and said electro-acoustical transducer;
- and
- a hearing aid signal processor having a recess therein in which said unit is received, said unit being mechanically and electrically connected to said hearing aid signal processor and said hearing aid signal processor processing signals between said acousto-electrical transducer and said electro-acoustical transducer dependent on a hearing impairment of a user of the hearing aid device.
