  4. 2. Bone anchored hearing aids 'BAHAs' in children

    Author : Claudia Priwin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : BAHA; conductive hearing loss; unilateral hearing loss; children; audiometry; sound localization; speech audiometry; self-assessment; questionnaire; craniofacial abnormalities;

    Abstract : BACKGROUND: The technique for applying bone-anchored hearing aids (BAHAs) by the use of osseointegration is today widely established for both adults and children. The BAHA concept is suitable for patients with recurrent ear infections or car malformations who cannot use conventional hearing aids, which are placed altogether or partially in the ear canal.

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

    Author : Sabine Reinfeldt; Chalmers tekniska högskola; []
    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

  6. 4. A Novel Bone Conduction Implant System

    Author : Hamidreza Taghavi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  7. 5. The Bone Conduction Implant (BCI) - Preclinical Studies, Technical Design and a Clinical Evaluation

    Author : Hamidreza Taghavi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bone conduction implant; Amplitude modulation; Bone anchored hearing aid; Radio frequency power amplifier and inductive link; Long-term implantation.; Low-power systems; Implanted transducer;

    Abstract : The Bone Conduction Implant (BCI) system has been developed as an alternative to the percutaneous bone anchored hearing aid (BAHA) with the advantage that the skin is kept intact. The transducer is permanently implanted and attached to the skull via a flat surface contact to the temporal bone. READ MORE
