Road Traffic Noise Survey: Bristol 2009


Bristol City Council are supporting a survey of residents on road traffic noise being conducted by a Masters student at the University of Derby. Matt Kirby is trying to find out how the orientation of houses and the location of the bedrooms in houses affect the annoyance of people who are exposed to different levels of noise. He is working with Bristol because of our ability to interrogate our noise map to identify the properties that fall within noise bands. The survey was distributed on the 1st April (no joke!) to residents around the M32 and also gives residents the opportunity to have their say on noise through the askbristol.com site. The results will be published in September.

Soundwalks - Part 2

The other video from the Soundwalks project is below - this one features a moving chart of the actual noise values, as well as an updating map showing the location of the recording.

Soundwalks in Bristol

One of the work packages in the SILENCE Project, in which Bristol was a partner, was the compilation of Soundwalks for each of the partner cities. The video below shows the soundwalk from Queens Square to the Centre.
The purpose of a Soundwalk is to...

"describe acoustic ambience in an overall way, without any judgment on what is heard."

To analyse the soundscape is to list all types of sound sources. A majority of them are motor vehicles: cars, city buses, small trucks,… but there are also a lot of varied and pleasant sound signals in the urban environment like birds, the wind in the leaves, fountains, children, bar terraces or walkers' footsteps on the gravel…

A full report on the approach and results of the soundscapes work package is on the SILENCE web site.
