	Environmental Noise
		Noise originates from all sorts of industrial activities, ranging from small workshops to livestock activities (abattoirs), outdoor factories (eg, for stone crushing), and heavy industry.
		Because of this great variety of industrial noise sources and of the different characters of the noises they emit, with regard to frequency content and time history, it is very difficult to compile an inventory of people non-occupationally exposed to industrial noise which is both representative for a certain country and comparable with other countries.
		Environmental noise pollution is thus a European problem of growing extent and concern.

	Noise - Albuquerque's Environmental Story
		Noise, commonly defined as unwanted sound, is an environmental phenomenon to which man is exposed before birth and throughout life.
		Noise can also be considered an environmental pollutant, a waste product generated in conjunction with various activities of man. Under the latter definition, noise is any sound--independent of loudness--that may produce an undesired physiological or psychological effect in an individual and that may interfere with the social ends of an individual or group.
		Noise ordinances have been effective in reducing those irritable, noisy occurrences that can be controlled by developing standards and placing the responsibility on the noise maker.

	NPC Resources: Environmental Noise Booklet from Bruer & Kjaer
		Noise of this kind is typical for large diesel engines in trains, ships, and power plants and, since the noise is hard to muffle and spreads easily in all directions, it can be heard for miles.
		The annoyance due to a given noise source is perceived very differently from person to person, and is also dependent upon many non-acoustic factors such as the prominence of the source, its importance to the listener’s economy and his or her personal opinion of the source.
		Outdoor noise levels usually decrease with increasing distance from the source because of geometrical spreading of the noise energy over a bigger surface and absorption of the noise by the atmosphere and by the ground.

	Noise Center: Decibel Levels (Site not responding. Last check: 2007-10-27)
		To know if a sound is loud enough to damage your ears, it is important to know both the loudness level (measured in decibels, dBA) and the length of exposure to the sound.
		If you must be exposed to noise, it is recommended that you limit the exposure time and/or wear hearing protection.
		These are typical levels, however, actual noise levels may vary depending on the particular item.
