  • Sound transducer for insertion in an ear
    Patent number: 10206045
    Abstract: The invention relates to a sound transducer for producing sound vibrations, which can be inserted in an ear and can be used in particular for an implantable hearing aid. The sound transducer has at least one carrier layer and at least one piezoelectric layer, as a result of which a deflection via a bimorph principle is achieved, or a deflection can be detected by picking up a voltage.
    Type: Grant
    Filed: October 3, 2016
    Date of Patent: February 12, 2019
    Assignee: Vibrosonic GmbH
    Inventors: Dominik Kaltenbacher, Armin Schäfer, Jonathan Schächtele, Hans Zenner, Erich Goll, Ernst Dahlhoff, Paul Muralt, Janine Conde

  • Hearing aid and method for eliminating acoustic feedback in the amplification of acoustic signals
    Patent number: 9078073
    Abstract: In a hearing aid having a microphone to be arranged at a body of a user for capturing ambient sound, a loudspeaker for outputting the ambient sound after having been amplified on a frequency-dependent basis, and a signal processor, the signal processor is configured to amplify the sound such that the amplified sound is audible to the user, and to automatically re-adjust the gain by the following steps: selecting a tone having a specific frequency; outputting the tone and the amplified ambient sound via the loudspeaker as an output sound; capturing via said microphone an analysis sound composed of ambient sound and of a reflection of said output sound; extracting a reflection of the tone from the captured analysis sound; and determining a reflection component for the specific frequency of the tone; adjusting the gain in frequency-specific manner and based on the determined reflection component.
