scope:

This Standard provides guidelines for assessing the compatibility of various human uses of land with the actual or projected outdoor acoustical environment at a site. The total acoustical environment is characterized by the annual average of the total day-night adjusted sound exposure or the annual average of the adjusted day-night average sound level. This Standard is based on the long-term annoyance response of average communities as measured by the percent of a community that is highly annoyed.

NOTE Annex A contains designated land uses such as sports arenas where the total day-night sound exposure or the day-night average sound level without the adjustments may be more appropriate for assessments of compatible land use.

This Standard does not address the effects of short-term exposure of people to intrusive sounds in locations such as parks and wilderness areas. The Standard does not address other effects of noise such as sleep disturbance or health effects. The effects of aircraft noise on sleep can be found in ANSI S12.9- 2000 / Part 6. This Standard does not provide a method to predict the response of a community to shortterm, infrequent, or non-repetitive sources of sound.
