  1. 11. A few aspects of aircraft noise

    Författare :Crispin Dickson; Shafiquzzaman Khan; Mendel Kleiner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paired comparison; sorting based paired comparison; sorting algorithms; mergesort; quicksort; aircraft sound synthesis; aircraft noise; sound quality; tonal effects; angle positions; flight conditions; methods of equalization; cognition; Acoustics; Akustik;

    Sammanfattning : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.

  3. 12. Hearing-related symptoms among women - Occurrence and risk in relation to occupational noise and stressful working conditions

    Författare :Sofie Fredriksson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing Disorders; Noise; Occupational; Occupational Stress; Women; Working;

    Sammanfattning : A considerable amount of research has been devoted to the risk of noise-induced hearing loss among industry workers – the majority of whom are men. Much less research has been done in female-dominated human service occupations, including obstetrical care and preschools. LÄS MER

  4. 13. EVALUATION OF ACOUSTIC COMFORT IN APARTMENT BUILDINGS

    Författare :Nikolas Vardaxis; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic comfort; field measurements; noise annoyance; subjective responses;

    Sammanfattning : This thesis concerns assessment of acoustic comfort in apartment buildings. A new approach is followed, beyond noise annoyance investigation, which was the typical path so far. The latter involved acoustic descriptors, which characterize the structural components, being associated to self-reported noise annoyance. LÄS MER

  5. 14. Perception of disturbing sounds : Investigations of people with hearing loss and normal hearing

    Författare :Åsa Skagerstrand; Stefan Stenfelt; Susanne Köbler; Stig Arlinger; Arne Leijon; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perception; annoyance; loudness; hearing loss; Handikappvetenskap; Disability Science;

    Sammanfattning : The present thesis concerns the daily sound environment and the human perception of the same. The sound environment affects the possibility to be active in a communication. With background noise, it may be harder to hear desired signals, and when suffering from a hearing loss, negative effects of the background noise increase. LÄS MER

  7. 15. Perception of Sound and Vibration in Heavy Trucks

    Författare :Anders Genell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral balance.; meaning; low frequency; product sound quality; annoyance; emotional reactions;

    Sammanfattning : Interior truck cabin sound has for some time been a concern for manufacturers. Today reasonably low sound pressure levels have been achieved using passive absorption. However low frequency sound is difficult to passively absorb and will hence dominate the interior sound. LÄS MER
