A

The purpose of HUD's noise regulation is to encourage suitable separation between noise sensitive land uses, particularly housing, and major noise sources (i.e., roadways, railroads, and military and civilian airports). The Responsible Entity (typically a unit of local government or state) must determine whether there are any major roadways with 1,000 feet, railroads within 3,000 feet, and military or civilian airports (regulated by the Federal Aviation Administration) that are within 15 miles of the project. If the housing development (which includes reconstruction of a single family residential unit), is within these distances of one or more of these noise generators, then a noise calculation is required to determine the noise level. Noise is considered Acceptable when the exterior noise level is 65 DNL or less. Otherwise, attenuation measures must be incorporated into construction plans (66-75 DNL, Normally Unacceptable).  

For a detailed discussion of the noise calculation process, please see HUD's Guidance and Technical Assistance for Noise Abatement and Control and HUD's Noise Guidebook found on HUD's Environment website.
