Abatement Eligibility
Noise abatement in New Hampshire is generally in the form of a sound barrier or berm. The locations of these barriers are identified using a specific set of criteria set forth by the NH Department of Transportation (NH DOT) and the Federal Highway Administration (FHWA). An area is not considered eligible for noise abatement unless it meets ALL of the criteria set forth in the Department's Noise Policy.
