The sound insulation and acoustic performance of buildings has grown in importance over the past decades due to the trend for inner-city apartment living and multi-unit housing complexes. The proliferation of high-powered entertainment systems has also placed unprecedented demands on housing in terms of its acoustic performance.
Due to its high-density, concrete has advantages over lightweight construction materials in various aspects of acoustic performance, specifically reducing airborne noise transmission, reducing noise from exterior sources and providing sound separation between adjoining rooms.
While exposed concrete may heighten impact sound, various integrated design solutions have been developed to address the problem of incorporating an adequate degree of acoustic absorbency without reducing the thermal functionality of an exposed concrete surface.
The overall sustainability implications of concrete’s acoustic absorption properties lie in the potential to enhance building occupants’ productivity, health and wellbeing.
