  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.

  4. 2. Investigations of neural attractor dynamics in human visual awareness

    Author : David N. Silverstein; Pawel Herman; Martin Ingvar; Karl Friston; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; attractor dynamics; visual awareness; visual perception; visual attention; attentional blink; backward masking; gliomas; brain tumor; white matter; cell assemblies; neocortical model; threat response; fear signaling; amygdala; Biological Physics; Biologisk fysik; Computer Science; Datalogi; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. READ MORE

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

    Author : Shahram Moradi; Jerker Rönnberg; Björn Lidestam; Linköpings universitet; []
    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

  7. 5. Effects of visual load on auditory processing

    Author : Malina Szychowska; Stefan Wiens; Mats E. Nilsson; Maria Larsson; Inga Griskova-Bulanova; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; EEG; event-related potential; mismatch negativity; auditory steady-state response; envelope following response; perceptual load; visual load; task difficulty; crossmodal attention; early-filter theory; adaptive filtering model; Psychology; psykologi;

    Abstract : In daily life, people need to be able to focus on a task while ignoring any task-irrelevant background noise. For example, people who work in an open-space office may have to work on a report while ignoring the background talk among co-workers. READ MORE
