This session is in order to consider methods of predicting noise in buildings with an emphasis on noise from mechanical services systems and domestic appliances. Mechanical services include: heating and ventilation systems, piped water systems, internal transportation systems. Domestic appliances include: central heating units, washing machines and cleaning and food processing appliances. Previously, the complexity of the sound transmission process, involving airborne, structure-borne and pipe-borne transmissions, has prevented the development of measurement and prediction methodologies of use to manufacturers, building engineers and legislators concerned with noise control. There has been progress in the prediction of noise resulting from airborne, impact and duct-borne impact sound sources. There has been less progress in the prediction of structure-borne and pipe-borne sound transmission. Similarly, there has been progress in the prediction of sound transmission in heavyweight homogeneous building structures but there has been less progress for the case of lightweight non-homogeneous constructions. This session welcomes contributions from researchers who are developing laboratory test procedures for characterising sound sources and also the transmission characteristics of walls and floors; also, for those implementing recently introduced standard prediction methods for airborne and impact sound transmission between rooms, and between the inside and outside of buildings.
