     We show an amazing tolerance for a form of pollution that is a growing problem: noise. Airplane traffic

is increasing by five percent a year. Urban noise is doubling every ten years. By air, land and sea, we are

facing an onslaught of noise that is threatening our ability to live in this world. We have granted ourselves

the right to make noise. But what about our responsibilities? Have we developed a sense of acoustic

responsibility?

     The evidence suggests that we have not. Many people seem to believe they have an unlimited right to

make noise with cars and motorbikes, and with loud music at home and in the street. In some countries

measures have been taken to force people to make less noise. In Britain, for example, a law has been

passed preventing people from disturbing their neighbors with music at night.

     It is widely accepted that we should deal with our rubbish in a responsible way. Noise is in reality a

particularly insidious form of rubbish. It destroys community life, pursues us into our homes, keeps us

from sleeping and is the cause of many stress-related illnesses, as well as hearing loss. Our acoustic

environment belongs to all of us. Everyone has the right to use it, but no one has the right to abuse it.

Let's start using it responsibly.
