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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Shahram Moradi; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2014]
    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

  4. 4. Phenomenological modelling of sensory integration phenomena using self-organized feature maps

    University dissertation from Luleå tekniska universitet

    Author : Tamas Jantvik; Luleå University of Technology.; Luleå University of Technology.; Luleå University of Technology.; [2011-12]
    Keywords : ;

    Abstract : The main contribution of the work presented herein is a method of transferring information from one lattice of artificial neural units to another. The essence of the present method consists of four parts: (1) the wrapping of the artificial neural lattice into a module that given an input to this lattice outputs normalized coordinates for the location of peak activity and the magnitude of the activity at that location; (2) the inter-module exchange of information being carried out by using the coordinates of the neuron that respond the strongest to the input given to the artificial neural lattice; (3) the concept of the transformation map which re-maps normalized coordinates from one module's output space on another's; and (4) fusion carried out by summation of activity fields induced by artificial neural lattices.

  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 : NATURVETENSKAP; NATURAL SCIENCES; Visual ecology; Animal vision; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    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
