  1. 1. Auralisation of airplanes considering sound propagation in a turbulent atmosphere

    Författare :Frederik Rietdijk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auralisation; Aircraft noise; Outdoor sound propagation; Atmospheric turbulence;

    Sammanfattning : Aircraft noise is a major issue in urban areas. Due to a rising level ofurbanisation and the continuing growth of air traffic more people are exposed toaircraft noise than ever. Methods currently used for assessing theimpact of aircraft noise on humans consider mostly energetic quantities, and not thedynamic character of the sound. LÄS MER

  3. 2. Auralisation of partial sound sources

    Författare :Nicklas Frenne; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : This Licentiate thesis focuses on the development of a method for auralisation of partial sound sources. In many work environments, noise is a primary annoyance factor. A specific problem is the masking of important aural information either by high noise levels or by too efficient sound insulation. LÄS MER

  4. 3. Background road traffic noise synthesis

    Författare :Georgios Zachos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; background traffic noise synthesis; auralisation; urban sound planning;

    Sammanfattning : As urban planning evolves along with societal life, new requirements that should be met are rising. One of those, is the inclusion of acoustic quality in urban environments, before, during, or after a planning process. To address this for a yet to be built area, metrics are needed that try to quantify acoustic quality. LÄS MER

  5. 4. Methods for product sound design

    Författare :Arne Nykänen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Product sound design has received much attention in recent years. This has created a need to develop and validate tools for developing product sound specifications. LÄS MER

  7. 5. Simulating rolling noise on ballasted and slab tracks: vibration, radiation, and pass-by signals

    Författare :Jannik Theyssen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway rolling noise; Numerical modelling; Green s functions; Time domain; Spherical harmonics; Slab track; 2.5D FE BE;

    Sammanfattning : Shifting to rail-bound freight and passenger traffic is key in Europe's strategy towards transport decarbonisation. However, increasing railway traffic can increase environmental noise pollution. Rolling noise is often the dominant noise source. It originates from the interaction of the rough running surfaces of wheel and rail. LÄS MER
