   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. 4. A Novel Bone Conduction Implant System

   Författare :Hamidreza Taghavi; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vibrations; audiological tests; Bone Anchored Hearing Aids; Bone Conduction; comparative study; Bone Conduction Implant; transcutaneous;

   Sammanfattning : 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. LÄS MER
