  • Transducer apparatus for high speech intelligibility in noisy environments
    Patent number: 11146884
    Abstract: A transducer apparatus to provide high speech-intelligibility in a noisy environment. The transducer apparatus comprises a vibration-sensing transducer adapted to be placed on the non-honey and non-cartilaginous, i.e., fleshy, part of the head of the user—either on the all-flesh part of the cheek or all-flesh under chin. The vibrations sensed are vibrations arising from the user's voice in his mouth and conducted to the surface of the fleshy area of the users cheek or under-chin, and not by bone vibration. The embodiments of the invention include its application into headsets, earsets and helmets; and a switching means; and a means to realize a vibration transducer from an acoustical microphone.
