  1. 1. Bone Conduction Hearing in Human Communication - Sensitivity, Transmission, and Applications

    University dissertation from Chalmers University of Technology

    Author : Sabine Reinfeldt; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medicinsk teknik; Medical engineering; bone conduction; bone conduction microphone; communication system; sensitivity; one s own voice; occlusion effect; transmission; bone-anchored hearing aid; transcutaneous; bone conduction implant;

    Abstract : Sound perceived via Bone Conduction (BC) consists of vibrations transmitted to the cochleae through the skull bone from either one's own voice, the surrounding sound field, or a BC transducer. In two-way communication systems, BC is believed to improve the sound quality when used in specific environments, e.g. READ MORE

  2. 2. A Novel Bone Conduction Implant System

    Abstract : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

    Abstract : Sound is conducted to the inner ear in two ways: by air and by bone. Air conduction (AC) hearing consists of sound waves entering the ear canal and reaching the cochlea, the main hearing organ, via the middle ear. In bone conduction (BC) hearing, instead, the transmission is through soft tissues and bone. READ MORE

  4. 4. A New Audiometric Bone Vibrator, Radioear B81, and the Bone Conduction Implant with Emphasis on Magnetic Resonance Imaging

    University dissertation from Chalmers University of Technology

    Author : Karl-Johan Fredén Jansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balanced electromagnetic separation transducer; bone conduction; bone vibrator; retention magnet; image artifact; demagnetization; magnetically induced torque; magnetic resonance imaging.;

    Abstract : Hearing by air conduction (AC) and bone conduction (BC) are attributed to be the natural ways of stimulating the cochlea. With AC hearing, the cochlea is stimulated by air pressure variations via the ear canal, whereas with BC hearing, sound vibrations are transmitted thru the skull bone to the cochlea. READ MORE

  5. 5. The Balanced Electromagnetic Separation Transducer for Bone Conduction Audiometry and Hearing Rehabilitation

    University dissertation from Chalmers University of Technology

    Author : Karl-Johan Fredén Jansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]

    Abstract : Hearing via air conduction (AC) and bone conduction (BC) are attributed to bethe natural ways of conducting sound to the cochlea. With AC hearing, air pressurevariations are transmitted to the cochlea via the ear canal, whereas with BChearing, sound vibrations are transmitted through the skull bone to the cochlea. READ MORE
