  2. 1. Sleep disordered breathing at work : Cause and effects

    Author : Jan Ulfberg; Uppsala universitet; []
    Keywords : Medical sciences; Snoring; sleepiness; sleep apnea; epidemiology; organic solvents; work performance; occupational accidents; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The recent discovery of obstructive sleep apnea syndrome (OSAS) as a prevalent disorder has highlightedthe fact that snoring is not just a harmless noise. Snoring and OSAS in the work milieu has hardly beeninvestigated, which makes it important to identify both risk factors and consequences in the work place. READ MORE

  4. 2. 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

  5. 3. Noise in the preschool : health and preventive measures

    Author : Fredrik Sjödin; Ulf Landström; Anders Kjellberg; Anders Knutsson; Mats Nilsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Noise; hearing disorders; stress; health; occupational environment; preventive measures; intervention; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : This thesis is based on noise recordings and health evaluations carried out at preschools in the northern part of Sweden. Sound level recordings were made on individuals and by use of stationary devices in dining rooms and play halls. Health evaluations were based on ratings by use of questionnaires and by analyses of cortisol. READ MORE

  6. 4. 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

  7. 5. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Abstract : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. READ MORE
