Noise in Cities
Past research focused on noise level (measured in decibels) and people’s responses.
Noise ‘maps’
- show that the highest noise levels are usually found on roads
- do not show other sources of noise, e.g. when windows are open or people’s neighbours are in their 1
- ignore variation in people’s perceptions of noise
- have made people realize that the noise is a 2 issue that must be dealt with
Problems caused by noise
- sleep disturbance
- increase in amount of stress

Different types of noise

What people want
Plenty of activity in urban environments which are 6, but also allow people to relax
But architects and town planners
- do not get much 7 in acoustics
- regard sound as the responsibility of engineers
Understanding sound as an art form
We need to know
- how sound relates to 8
- what can be learnt from psychology about the effects of sound
- whether physics can help us understand the 9 of sound
Virtual reality programs
- advantage: predict the effect of buildings
- current disadvantage: they are 10
