Abstract

Building structures can be excellent transmitters of impact noise.  As urban density increases, the use of rooftops to regain exterior private and/or public spaces escalates. Noise generated on the roof due to mechanical units, maintenance personnel and amenity uses is usually underestimated and not considered in building design. Consideration of the insulation of impact noise is of great importance particularly when the roof is a light weight structural system. C measures were performed on the exposed membrane of a conventional light weight roof; and with pavers, wood deck, 75mm depth green roofs and 150 mm green roof. The IIC of the green roofs were 20 higher than the exposed membrane and 14 - 20 higher than traditional roof deck materials.
