• Including the irregularities in the light-weight floor/ceiling model

      Chung, H; Fox, C (The Institute of the Noise Control Engineering of the USA, 2006)
      Chung and Fox previously presented a mathematical/computational model giving good prediction of low-frequency vibration of light-weight timber based floor/ceiling structures (LTFS) made up of: upper plate, joist beams and ...
    • Lightweight floor/ceiling systems with improved impact sound insulation

      Chung, H; Fox, C; Dodd, G; Emms, G (The New Zealand Acoustical Society, 2010)
      Contrary to common belief, a relatively simple and practical lightweight timber based floor/ceiling can have impact sound insulation superior to that of concrete slab based systems. This paper presents examples of such ...
    • Transition conditions at the interface between floating plates

      Chung, H; Fox, C (The International Workshop on Water Waves and Floating Bodies (IWWWFB), 2005)
      This paper presents studies of wave propagation across a crack in an ice sheet. We consider a crack between two ice sheets that are infinitely stretching to either side. The theoretical model of the ice sheet assumes that ...
    • Vibration of lightweight rib-reinforced structures with random irregularities

      Chung, H; Fox, C (Institutes of Acoustics, Chinese Academy of Sciences and Acoustical Society of China, 2008)
      This paper describes mathematical modelling procedure of the rib-reinforced floor/ceiling structures, which are made up of components with irregular shapes and physical parameters. Exact determination of the vibration of ...
