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 31
ignore variation in people’s perceptions of noise
have made people realize that the noise is a 32 issue that must be dealt with
Problems caused by noise
sleep disturbance
increase in amount of stress
effect on the 33 of schoolchildren
Different types of noise
Some noises can be considered pleasant e.g. the sound of a 34 in a town
To investigate this, researchers may use methods from 35 sciences e.g. questionnaires
What people want
Plenty of activity in urban environments which are 36, but also allow people to relax
But architects and town planners
do not get much 37 in acoustics
regard sound as the responsibility of engineers
Understanding sound as an art form
We need to know
how sound relates to 38
what can be learnt from psychology about the effects of sound
whether physics can help us understand the 39 of sound
Virtual reality programs
advantage: predict the effect of buildings
current disadvantage: they are 40
