  1. 6. A digital filterbank hearing aid

    Författare :Thomas Lunner; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Digital signal processing hearing aids may provide possibilities for new signal processing strategies to compensate for hearing loss. However, to be practically usable in a headworn hearing aid the digital circuitry needs to fulfil requirements of low power consumption, low supply voltage and small size. LÄS MER

  3. 7. Sound quality assessment using binaural technology

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

    Sammanfattning : This licentiate thesis contains experimental work about the use of binaural technology for assessment of sound quality. Binaural technology aims to measure sound in the way compatible with human hearing. For that purpose artificial head with the microphones in the position of the ears is used. LÄS MER

  4. 8. 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. 9. 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

  7. 10. Supra-threshold hearing loss and wide dynamic range compression

    Författare :Henrik L Olsen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Hearing impairment; compression; hearing aids; modulated noise; speech intelligibility; temporal resolution; modulation transfer function;

    Sammanfattning : Cochlear hearing loss leads to deficits in many perceptual aspects, including threshold elevation (loss of sensitivity), reduction of auditory dynamic range (loudness recruitment) and problems with resolving sounds (loss of supra-threshold hearing). An ongoing debate is whether assessment of the individual supra-threshold hearing provides information which is likely to have an important influence on clinical decisions on signal processing strategies.
