  2. 6. Low-frequency components in complex noise and their perceived loudness and annoyance

    Author : Mikael Goldstein; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hörsel;

    Abstract : Olika ljudtrycksbaserade prediktorers (A-, B-, C- & D-filtret) och kalkyleringsmetoders (ISO 532 B & MARK VII) förmåga att predicera ljudstyrka och störningsgrad hos bredbandigt vitt brus presenterat inomhus med olika bandbredd och spektra-form, inom frekvensområdet 15-1,060 Hz, innehållande både en "lågfrekvent" och en "högfrekvent" frekvenskomponent, utvärderades. Fem studier innehållande sju experiment, där mellan 12-30 försökspersoner deltog, avrapporteras. READ MORE

  4. 7. A Dynamic View of Melodic Organization and Performance : Perception of Structure and Emotional Expression in Music

    Author : Erik Lindström; Alf Gabrielsson; Andreas C. Lehmann; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; accents; emotion; expression; musical structure; tonal structure; Psykologi; Psychology; Psykologi;

    Abstract : Psychology of music has shown renewed interest in how music expresses emotion to listeners. However, there is an obvious lack of research on how interactions between musical factors such as harmony, rhythm, melodic contour, loudness, and articulation may affect perceived emotion. READ MORE

  5. 8. Supra-threshold hearing loss and wide dynamic range compression

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

    Abstract : 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.

  6. 9. Perspectives on wanted and unwanted sounds in outdoor environments : Studies of masking, stress recovery, and speech intelligibility

    Author : Jesper J. Alvarsson; Mats E. Nilsson; Stefan Wiens; Staffan Hygge; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; psykologi;

    Abstract : An acoustic environment contains sounds from various sound sources, some generally perceived as wanted, others as unwanted. This thesis examines the effects of wanted and unwanted sounds in acoustic environments, with regard to masking, stress recovery, and speech intelligibility. READ MORE

  7. 10. Methods for specification of sound quality applied to saxophone sound

    Author : Arne Nykänen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : Product specifications that include descriptors of sound qualities are most helpful when a description contains adequate detail and utilises understandable wording. Good specifications require that any descriptions used are familiar to users and that these descriptions are interpretable as acoustical quantities. READ MORE
