I have previously suggested that the ACCC could get involved in reviewing claims made by marketers of wooden floors. To say that a particular reduction of sound transmission, recorded by a testing system that is not necessarily univerally accepted, meets the requirements of ‘strata’ is frankly misleading when the general standard of ‘strata’, in NSW at least, is expressed in the model by-law requiring that floors be covered in a way that prevents noise transmission likely to disturb neighbours’ quiet enjoyment of their homes. There does seem to be widespread use of pseudo-science to exploit the ignorant. How many of us have a true understanding of the physics of sound and the various ways it is measured, let alone the physiology of its interaction with the human brain?
