  1. 6. Effects of age and stimulation strategies on cochlear implantation and a clinically feasible method for sound localization latency

    Författare :Martin Eklöf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Treating prelingual deafness with cochlear implants paves the way for spoken language development. Previous studies have shown that providing the intervention at six to 11 months is better than at 12-17 months. LÄS MER

  3. 7. 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

  4. 8. Sparse Modeling of Grouped Line Spectra

    Författare :Ted Kronvall; Statistical Signal Processing Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; line spectra; parameter estimation; convex optimization; group-sparsity; block-sparsity; dictionary learning; ADMM; adaptive penalty; total variation; multi-pitch estimation; chroma; audio processing; TDOA; near-field localization; amplitude modulation;

    Sammanfattning : This licentiate thesis focuses on clustered parametric models for estimation of line spectra, when the spectral content of a signal source is assumed to exhibit some form of grouping. Different from previous parametric approaches, which generally require explicit knowledge of the model orders, this thesis exploits sparse modeling, where the orders are implicitly chosen. LÄS MER

  5. 9. Applications of Signal Processing to Microphone Node Calibration and Medical Signal Classification

    Författare :Zhayida Simayijiang; Mathematical Imaging Group; []
    Nyckelord :ToA; TDoA; Sensor Network Localization; EEG; CTG; machine learning.;

    Sammanfattning : Localization is an important enabling technology for many applications, such as wireless sensor networks, emergency rescue services, civil defense and transportation. Suppose that a room is equipped with several microphones (or sensors), and one person is making a sound while moving around in the room. LÄS MER

  7. 10. 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.
