4. 2. 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. Annoyance, quality- and safety aspects of sound in truck cabins

   Author : Anders Genell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral balance; low frequency; product sound quality; annoyance;

   Abstract : For heavy vehicles the interior sound environment is still more or less just apassive result of the engineering of the different parts that make up the vehicle,although measures are taken to keep sound pressure level within legislatedboundaries. Additionally, the sound inside truck cabins is dominated by itslow frequency (LF) content, and is hence prone to impair task performance andreduce wakefulness as well as cause general annoyance and different adversehealth effects.

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. Road Traffic Noise - Factors modifying its relation to annoyance and cardiovascular disease

   Author : Theo Bodin; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Road Traffic Noise; Annoyance; Myocardial Infarction; Hypertension; Sleep;

   Abstract : Traffic noise causes annoyance and sleep disturbance and has been linked with several other adverse effects on life quality and health, including increased risk of hypertension and myocardial infarction. Conservative estimates assume that at least one million healthy life years are lost every year from traffic related noise in the western part of Europe. READ MORE
