ANSI/ASA S12.9-1996 - Part 4 (R2001)
This standard specifies methods to assess environmental sounds and to predict the annoyance response of communities to long-term noise from any and all types of environmental sounds produced by distinct or distributed sound sources.
Vendor Note: This standard specifies methods to assess environmental sounds and to predict the annoyance response of communities to long-term noise from any and all types of environmental sounds produced by one or more distinct or distributed sound sources. The sound sources may be separate or in various combinations. Application of the method of the standard is limited to areas where people reside and related long-term land uses. This standard does not address the effects of intrusive sound on people in areas of short-term use, such as parks and wilderness areas, nor does it address other effects of noise such as sleepdisturbance or health effects. This standard does not provide a method to predict the community response to short-term, infrequent, non-repetitive sources of sound.
