  1. 1. Game engine based auralization of airborne sound insulation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jimmy Forsman; [2018]
    Nyckelord :Auralization; Building acoustics; Airborne sound insulation; EN 12354-1; Room acoustics; Audio engines for virtual reality; Game engine;

    Sammanfattning : Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians. When developing infrastructure, tools for decision making needs to address visual and aural perception. LÄS MER

  3. 2. Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet

    M1-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Denis Corluka; Samuel Lönnqvist; [2014]
    Nyckelord :Homogena betongelement; Masslag; SS-EN 12354-1; Densitet; Bastian; Ytvikt; Reduktionstal; Luftburet ljud.;

    Sammanfattning : Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. LÄS MER

  4. 3. Beräkningsstandard för ljudisolering

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik

    Författare :Margot Hansson; [2006]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this Master Thesis is to observe how well the standard EN 12354, the computer program Bastian, and field measurements agree with each other. Calculations on two different objects, where one object cointained four different constructions, were compared with data from field measurments. LÄS MER
