Designing residential buildings to meet the NCC (BCA) and other internal noise criteria such as AAAC star rating guide. Wall and Floor certification testing to BCA and Body Corporate noise impact criteria (performance descriptors: Lntw, FIIC, STC, Rw)















Field Floor Impact Certification Tests for body corporate by laws and building code certification field testing. We use a “tapping machine” to strike a floor surface and measure the transmitted noise below the impact testing machine. A useful rating guide to make sense of floor impact numbers can be found at the Association of Australian Acoustical Consultants website (Ref: AAAC Guideline for Apartment and Townhouse Acoustic Rating 2010)
