Noise Disturbance

Building acoustics can help to mitigate the effects of noise disturbance which can have negative effects on health, well-being and general quality of life.

The Noise Policy Statement for England (NPSE) defines noise pollution as:

- Environmental noise: which includes noise from transportation sources. - Neighbour noise: which includes noise from inside and outside buildings. - Neighbourhood noise: which includes noise arising from industrial and entertainment premises, trade and businesses, construction sites and noise in the street.

This can be an important consideration for the location, design and construction of new developments.
