Neighbour noise is a significant problem having had insufficient attention for decades, both for existing housing and new housing. Time had come to solve the challenges by establishing a common framework in building acoustics throughout Europe. As a consequence, the research network, COST Action TU0901 “Integrating and Harmonizing Sound Insulation Aspects in Sustainable Urban Housing Constructions” was established to initiate and support a process towards such framework.
COST TU0901 considered the main tool to be an acoustic classification scheme for dwellings –implying definition of a number of quality classes– combined with knowledge about housing constructions complying with the class criteria.
