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

    Author : Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; wind turbines; noise annoyance; sound perception; 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.

  5. 3. Classroom noise : exposure and subjective response among pupils

    Author : Pär Lundquist; Rauno Pääkkönen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; school; teaching; students; annoyance children; sound; mood;

    Abstract : In Sweden, all children must have access to education of equal value and the curriculum points out the importance of a good environment for development and learning. Modern working methods differ a lot from the traditional. Teaching nowadays is focused on problem-solving. Students are more interactive, working in groups and projects. READ MORE

  6. 4. Low frequency noise during work. Effects on performance and annoyance

    Author : Johanna Bengtsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low frequency noise; performance; workload; annoyance; cortisol; subjective stress; subjective sensitivity to noise; sound characteristics; frequency balance; modulation frequency;

    Abstract : Aims. Low frequency noise (LFN) is defined as "a noise with a dominant frequency content of 20 to 200 Hz". Common sources of LFN in occupational environments are ventilation, heating and air-conditioning systems, computer network installations and compressors. READ MORE

  7. 5. Noise from wind turbines

    Author : Olivier Fégeant; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; masking; vibration transmission; diffraction; ambient noise; pseudo-noise; cylindrical shell. Perturbation methods; structural mobility; axoustic outdoor measurement; Building engineering; Byggnadsteknik;

    Abstract : A rapid growth of installed wind power capacity is expectedin the next few years. However, the siting of wind turbines ona large scale raises concerns about their environmental impact,notably with respect to noise. READ MORE
