  • Patent number: 12284486
    Abstract: In the method according to the invention for actively suppressing the occlusion effect during the playback of audio signals by means of headphones or a hearing aid, a sound signal occurring from outside is captured by means of at least one outer microphone of the headphones or the hearing aid. A voice signal is captured by means of at least one additional microphone. The dry component of the captured voice signal is estimated, the dry component of the captured voice signal being the component of the captured voice signal without reverberation caused by the surrounding space. By means of a filter, a voice component is extracted from the outer sound captured using the at least one outer microphone. The extracted or produced voice component is output by means of a loudspeaker of the headphones or the hearing aid.

  • Patent number: 12279094
    Abstract: Acoustic valve for a hearing device, including a valve body defining a passageway, and a seat member and shutter member inside the valve body. The shutter member defines a shutter surface that forms a contact portion and a non-contact portion. The shutter member is moveable relative to the seat member to transition the valve between an opened state, wherein the shutter member is removed from the seat member and the passageway is open to allow sound to pass, and a closed state wherein the contact portion abuts the seat member and the non-contact portion blocks the passageway to restrict passage of sound. The contact portion forms a protruding structure that extends from the non-contact portion and towards the seat member, and has a small width along at least one transverse direction to minimise a contact area between the contact portion and the seat member when the valve is closed.
