PhD prediction and measurement of rain noise

Rain noise is an important consideration nowadays in the design of schools, sports halls and many other buildings. A standard measurement method was introduced in 2006 (ISO 140:18 - based largely on research carried out at Salford during the early 1990s) which allows roof constructions to be characterised and rated in terms of their rain noise performance. The current rain noise research aims to extend earlier work so as to develop faster and more adaptable measurement methods as well as prediction models. It will also extend the ‘Rain Noise Simulator’, developed during various student projects; the simulator produces realistic simulated sounds of any type of rainfall falling on a roof tested in ‘dry’ conditions, i.e. without any real or artificial rainfall.
