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

-    effect on the 3 of schoolchildren

Different types of noise

To investigate this, researchers may use methods from 5 sciences e.g. questionnaires

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
