Overland warehouse impact sound rating tests and mass timber implications

Impact sound rating tests were conducted at the Overland Warehouse. This historic building aims to add sleeping rooms and was required to achieve Normalized Impact Sound Ratings of not less than 45 if field tested with ASTM E1007. Many considerations of ASTM E1007 assume flooring construction that does not match the Overland floor ceilings. Repeated tests of the same construction on two different levels of the building and at two locations within the same receiving rooms provide some insight into unique considerations.
