  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. 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

  4. 4. Breast Tomosynthesis: Aspects on detection and perception of simulated lesions

    University dissertation from Medical Radiation Physics

    Author : Pontus Timberg; Lunds universitet.; Lund University.; [2011]
    Keywords : MEDICIN; MEDICINE;

    Abstract : The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. READ MORE

  5. 5. 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 : Visual ecology; Animal vision; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes; Biologi; Biology;

    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
