Sound Impact Properties of Precast Concrete

National Precaster (May 2006) addressed the air-borne sound properties of precast concrete i.e. the transmission and insulation of air borne sound from outside noise sources to interior environments, where precast cladding and glazing were the predominant building materials used in construction.

Acoustic Properties of Precast Concrete - National Precast

150 mm thick precast concrete panel is an interesting situation in respect to compliance with the Building Code of Australia. The typical laboratory performance of a 150 thick precast wall is Rw 54 and the Ctr is -5 giving an overall rating of Rw + Ctr equalling 49 dB. Technically this does not comply with the BCA, which requires 50 dB and there has been experience with some certifiers that will not approve a 150 precast concrete
