  1. 1. Bone conducted sound transmission for communication systems

    Författare :Sabine Reinfeldt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone conduction; sound field hearing; occlusion effect; transcranial transmission; communication system; bone conduction microphone; hearing protection devices; hearing;

    Sammanfattning : 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. LÄS MER

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

    Författare :Sabine Reinfeldt; Chalmers tekniska högskola; []
    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. Binaural technology and issues related to sound quality analysis and spatial hearing

    Författare :Donatas Trapenskas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Binaural technology makes it possible to record, store and reproduce sound field in a perceptually authentic way, i.e. recorded sounds are correctly reproduced so that it is as if the listener was present in the recorded environment. This method involves recording and correctly reproducing sound pressures at each of the eardrums of the listener. LÄS MER

  5. 4. Impact on participation and service for persons with deafblindness

    Författare :Kerstin Möller; Berth Danermark; Claes Möller; Rune Simeonsson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; deafblindness; ICF; participation restriction; service barrier; Usher Syndrome; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Social sciences; Socialvetenskap; Social work; Socialt arbete; Disability research; Handikappsforskning; Medicinsk handikappvetenskap; Medical Disability Research;

    Sammanfattning : Persons with deafblindness experience difficulties in daily life and they experience service to sometimes barrier. The overall aim of this thesis is therefore to discover, evaluate and explain: 1. mechanisms that might have impact on participation restrictions for people who have visual and hearing impairment i.e. LÄS MER
