ABSTRACT
Though important to the economic health of any community, transportation is the major source of noise because it is so pervasive. The sound quality of areas adjacent to airports, freeways, turnpikes, and commuter railroads is seriously degraded by the noise emitted by these sources. Aircraft arriving and leaving the commercial and general airports must be counted in any inventory of community noise sources. Transportation noise, in general, except in the vicinity of airports and highways, is transient. The noise from a passing truck or airplane intrudes on the environment and is soon gone. But industrial noise, while it affects relatively few people, is part of a community for a long time. Domestic noise sources, including those in the home as well as those out of doors, are widely distributed. The major effect of community noise is that it makes person-to-person communication more difficult.
