  2. 2. Transmission of structure-borne sound in ships : applications to a prediction model

    University dissertation from Institutionen för farkostteknik

    Author : Ulf Orrenius; KTH.; [1997]
    Keywords : ;

    Abstract : This thesis examines transmission of structure-borne soundin rib-stiffened plate structures. In particular, theapplication of a prediction model for ships is analysed. Thismodel is based on a waveguide description of the structure. READ MORE

  3. 3. Structure-borne sound properties of vibration isolators

    University dissertation from Stockholm : KTH

    Author : Leif Kari; KTH.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis consists of four papers concerning the audibledynamic stiffness of a vibration isolator; includingmeasurements and theoretical modeling. The study focus isrubber isolators, being the most popular material in theaudible frequency domain - though the measurement principlealso applies to other resilient elements. READ MORE

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

  5. 5. The effects of damping treatment on the sound transmission loss of honeycomb panels

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sathish Kumar Ramanathan; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sandwich Structures; Honeycomb Panels; Sound Transmission; Loss Factor; Damping; Sound Radiation; TECHNOLOGY Engineering physics Acoustics; TEKNIKVETENSKAP Teknisk fysik Akustik;

    Abstract : In the industry, all passenger vehicles are treated with damping materials to reduce structure-borne sound. Though these damping materials are effective to attenuate structure-borne sound, they have little or no effect on the air-borne sound transmission. READ MORE
