摘要：
The sound insulation properties of lightweight aggregates (composite materials) are researched there. Four different porous aggregates and one concrete sample were made to test sound insulation properties. The samples were used for experiment as sound insulators between noise source and microphone in dual chamber case (Fig. 1). Measurements were taken at 1/2 octave intervals from 31.5 Hz to 16000 Hz and compared.
