Reducing the level of noise

We cannot escape noise in our daily lives and seem to accept the physiological and psychological harm it causes.

Though we have long realized it affects our environment and is a threat to our health, noise in all areas, especially in the urban ones, has been increasing rapidly. It seems to be everywhere, inside buildings, out on the streets, up in the sky and even under the ground.

The results of a recent investigation into noise pollution in 10 cities show that it is very serious in big cities.
