  1. 1. Airborne sound insulation of single and double plate constructions

    Author : Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Abstract : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. READ MORE

  3. 3. Sound Insulation at Low Frequencies

    Author : Andrzej Pietrzyk; Chalmers University of Technology; []
    Keywords : Finite Element Method; numerical simulations; Modal Approach; sound insulation; sound reduction index; low frequency; building partitions;

    Abstract : The airborne sound transmission through building partitions at low frequencies was studied. The definition of the sound reduction index as a measure of sound insulation has been examined by means of extensive numerical simulations in 3-D domains. The simulations were based on the wave theoretical acoustics. READ MORE

  4. 4. Measurement and perception of sound insulation from 20 Hz between dwellings

    Author : Rikard Öqvist; Fredrik Ljunggren; Roger Johnsson; Anders Ågren; Berndt Zeitler; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound insulation; Lightweight constructions; Annoyance; Measurement uncertainty; Low frequency; Building Acoustics; Walking noise; Teknisk akustik; Engineering Acoustics;

    Abstract : Population growth and urbanization are projected by the United Nations to add 2,5 billionpeople to the world’s urban population by 2050. We need to construct buildings in anunprecedented scale to meet global housing demand. Sustainable development is critical. READ MORE

  5. 5. Acoustic excitation and transmission of lightweight structures

    Author : Jonas Brunskog; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; point mobility; Lamb waves; wood.; Building construction; plate excitation; cavities; near-periodicity; nearly periodic; sound insulation; timber; structural acoustics; spatial Fourier transform; resilient device; prediction model; periodic; lightweight; ISO tapping machine; airborne noise; Building acoustics; impact noise; Byggnadsteknik;

    Abstract : In order to increase our knowledge of the sound transmission and radiation processes of lightweight wall and floor structures, theoretical models are needed. Detailed models may form a valuable tool. In lightweight floor structures, impact sound insulation is perhaps the most important property to consider. READ MORE
