The positive effects of quiet facades and quiet urban areas on traffic noise annoyance and sleep disturbance - QSIDE

Start date 01/09/2010
End date The project is closed: 31/08/2013

Traffic noise in European cities is a major source of annoyance and sleep disturbance. A good approach to reduce the harmful effects of traffic noise is to create quiet facades and quiet urban areas. The project QSIDE will provide strategies and tools to put this approach in practice.
Project objectives:
The main objective of the project QSIDE is to demonstrate how European cities can effectively reduce harmful effects of traffic noise (annoyance and sleep disturbance) by offering refuges to the inhabitants: quiet facades and quiet areas. For example, a quiet façade offers the possibility to choose a bedroom on the quiet side of a house, thereby reducing the chances on sleep disturbance by traffic noise. The refuges can be created in new urban areas, but they can also be created by modifying existing urban areas, for example by modifying traffic flows (see illustration below) or by choosing specific orientations of houses with respect to roads. The benefits of quiet facades and areas will be demonstrated by performing detailed traffic noise mapping calculations for cities, employing a new noise assessment methodology including the benefits from quiet facades and areas.


The project is carried out at the Divison of Applied Acoustics in the research group Vibroacoustics.
