  1. 1. Vibrations in timber floors Dynamic properties and human perception

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Kirsi Jarnerö; Linnéuniversitetet.; RISE.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Byggteknik; Civil engineering; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance;

    Abstract : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. READ MORE

  2. 2. Vibroacoustic performance of wooden buildings : Prediction and Perception

    University dissertation from Engineering Acoustics, LTH, Lund University

    Author : Juan Negreira; Lunds universitet.; Lund University.; [2016-04-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction tools; Low frequency vibrations; Vibroacoustics; Wooden buildings; Impact sound insulation; Finite element method; Vibration measurements; Flanking transmission; Elastomers; Design indicators; Vibration acceptability; Vibration annoyance; MEMS accelerometers;

    Abstract : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. READ MORE

  3. 3. Perception of Sound and Vibration in Heavy Trucks

    University dissertation from Engineering Acoustics, LTH, Lund University

    Author : Anders Genell; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral balance.; meaning; low frequency; product sound quality; annoyance; emotional reactions;

    Abstract : Interior truck cabin sound has for some time been a concern for manufacturers. Today reasonably low sound pressure levels have been achieved using passive absorption. However low frequency sound is difficult to passively absorb and will hence dominate the interior sound. READ MORE

  4. 4. Vibrations in Lightweight Buildings - Perception and Prediction

    University dissertation from Lund University. Department of construction science

    Author : Juan Negreira; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psycho-vibratory evaluation; Vibrations; Timber floors; Lightweight; Measurements; Serviceability criteria; Vibration annoyance; Vibration acceptability; Elastomer; Finite element method; Prediction Tools.;

    Abstract : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. READ MORE

  5. 5. Noise from wind turbines

    University dissertation from Stockholm : Institutionen för byggnader och installationer

    Author : Olivier Fégeant; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; masking; vibration transmission; diffraction; ambient noise; pseudo-noise; cylindrical shell. Perturbation methods; structural mobility; axoustic outdoor measurement; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur 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
