1. 1. Multichannel Audio Signal Processing : Room Correction and Sound Perception

   Författare :Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

   Sammanfattning : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. LÄS MER

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

   Författare :Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 3. Indoor Environment and User Perception. A Field Study in a Hospital Ward

   Författare :Jennie Skoog; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor environment; thermal climate; hospital ward; indoor air quality; comfort; perception; sound; light;

   Sammanfattning : The research on indoor environment has become more important and extensive the last decades. There is, however, a lack of studies made in buildings with two or more distinct groups of people. This study deals with hospital wards, which are a prime example of buildings occupied by more than one homogenous group of people. LÄS MER

5. 4. Perception of disturbing sounds : Investigations of people with hearing loss and normal hearing

   Författare :Åsa Skagerstrand; Stefan Stenfelt; Susanne Köbler; Stig Arlinger; Arne Leijon; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perception; annoyance; loudness; hearing loss; Handikappvetenskap; Disability Science;

   Sammanfattning : The present thesis concerns the daily sound environment and the human perception of the same. The sound environment affects the possibility to be active in a communication. With background noise, it may be harder to hear desired signals, and when suffering from a hearing loss, negative effects of the background noise increase. LÄS MER

7. 5. The psychophysics of human echolocation

   Författare :Carlos Tirado Aldana; Mats Nilsson; Daniel Västfjäll; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Detection; Individual differences; Human echolocation; Lateralization; Localization; Echobot; Psychology; psykologi;

   Sammanfattning : Echolocation is the capacity to detect, localize, discriminate, and, overall, gather spatial information from sound reflections. Since we began studying it in humans, we have learned several things. First, most humans can echolocate to some degree. LÄS MER
