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

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

    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. Direct Drive Bone Conduction Stimulation: Experimental Studies on Functionality and Transmission with Focus on the Bone Conduction Implant

    Author : Cristina Rigato; Chalmers University of Technology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; vibrations; audiological tests; Bone Anchored Hearing Aids; Bone Conduction; comparative study; Bone Conduction Implant; transcutaneous;

    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

  3. 3. On Direct Drive Bone Conduction Devices - Hearing Rehabilitation and Objective Assessment of Stimulation Methods

    Author : Cristina Rigato; Chalmers University of Technology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Bone Conduction Implant; audiology; comparative study; Direct Drive; active transcutaneous; vibrations; Bone Conduction Devices;

    Abstract : Bone conduction devices (BCDs) rely on the transmission of sound in form of vibrations generated by a transducer to the inner ear via the skull and surrounding soft tissues. Direct drive BCDs stimulate the skull bone directly, either via a skin-penetrating abutment (BAHAs, Bone Anchored Hearing Aids), or with a transducer implanted under intact skin (active transcutaneous devices).

  4. 4. Bone conducted sound transmission for communication systems

    Author : Sabine Reinfeldt; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone conduction; sound field hearing; occlusion effect; transcranial transmission; communication system; bone conduction microphone; hearing protection devices; hearing;

    Abstract : Bone conducted (BC) sound is vibrations in the skull bone that are transmitted to the cochlea and perceived as sound, originating from a sound field or a vibration transducer. This transmission path can be advantageous for communication systems in some situations, e.g. READ MORE

  5. 5. A Novel Bone Conduction Implant System

    Author : Hamidreza Taghavi; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

    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.
