Problems and explanation of noise in towns.

As more and more machinery and equipment come into routine use in our towns, noise levels continue to rise. At the present time levels are rising by around 25% every year. This introductory film gives a general survey of how noise is produced and explains in simple terms the way in which noise is received by the human ear as well as showing how noise can be measured and analysed.
