Noise consists of pressure fluctuations in the air that radiate from the noise source at high speed. Noise sources are classified according to (1) transportation industry, (2) industrial production and (3) citizen or user noise. Three methods are discussed for reducing the level of noise. They are (1) stop the noise at the source, (2) intercept the noise in its path between the source and the receiver, and (3) absorb the noise at the receiver of these three methods; only (1) is recommended. Case studies are presented showing that although hospitals in the Louisville metropolitan area have set a limit not to exceed 40 decibels more than 50% of the day, schools are in the process of attempting to establish the effects of traffic noise in classrooms, etc. It is stressed that planners must be more concerned about the environmental effects of the traffic from highways and on three urban areas which those highways traverse.
