    Abstract : Popular Abstract in Swedish Trumljud är det ljud som hörs i ett rum då ett objekt, till exempel en fot, träffar golvytan i samma rum. Ökande användning av tunna och hårda golvbeläggningar, såsom parkett och laminatgolv, kan leda till ljudstarka och skarpa ljud, vilket har ökat intresset av trumljud. READ MORE

  2. 2. A Virtual Design Studio for Low-Frequency Sound from Walking in Lightweight Buildings

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Nata Amiryarahmadi; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight floors; Annoyance; Walking sound; Virtual design studio; Low frequency;

    Abstract : In recent years there has been a growing interest for building lightweight multistorey wooden residential buildings in countries like Sweden with large and renewable forests. While positive aspects of these buildings, such as sustainability, ease of construction and lightness, motivate building more in wood, poor acoustic performance is a risk which concerns the wooden-building industry.

    Abstract : Background: Parkinson's disease (PD) is a chronic progressive neurodegenerative disease that results in functional loss and disability. People with PD have an increased risk of falling, and most of their falls occur while walking. As yet, there is limited knowledge concerning activity avoidance due to perceived risk of falling in people with PD. READ MORE

  5. 5. Assessing and modelling impact sound insulation of wooden joist constructions

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Wanqing Shi; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : Impact sound insulation is one of the most important aspects when assessing sound insulation of floor constructions in buildings. For assessing the impact sound insulation of aconstruction, a standard tapping machine is used as a sound source. READ MORE
