  1. 1. Human response to wind turbine noise ? perception, annoyance and moderating factors

    Author : Eja Pedersen; Göteborgs universitet.; University of Gothenburg.; Högskolan i Halmstad.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN; MEDICINE; wind turbines; noise annoyance; sound perception; audio-visual interaction; low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure;

    Abstract : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

  3. 3. Time is of the essence in speech perception! Get it fast, or think about it

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Shahram Moradi; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Noise; auditory speech perception; audiovisual speech perception; hearing aids; Buller; hörsel; auditiv talperception; audiovisuell talperception; hörhjälpmedel;

    Abstract : The present thesis examined the extent to which background noise influences the isolation point (IP, the shortest time from the onset of speech stimulus required for correct identification of that speech stimulus) and accuracy in identification of different types of speech stimuli (consonants, words, and final words in high-predictable [HP] and low-predictable [LP] sentences). These speech stimuli were presented in different modalities of presentation (auditory, visual, and audiovisual) to young normal-hearing listeners (Papers 1, 2, and 5). READ MORE

  4. 4. Bird Vision: Spatial acuity and colour discrimination in bright and dim light

    University dissertation from Department of Biology, Lund University

    Author : Olle Lind; Lunds universitet.; Lund University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visual ecology; Animal vision; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    Abstract : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. READ MORE

  5. 5. On Reverberation Enhancement in Auditoria

    University dissertation from Chalmers University of Technology

    Author : Peter Svensson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture; Teknisk mekanik; Engineering mechanics; room acoustics; electro acoustics; computer modelling of acoustics in enclosures; reverberation enhancement; active sound field control; sound-reinforcement; time-varying filters; feedback systems; feedback control; listening tests; modulation; subjective effects;

    Abstract : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. READ MORE
