# 49 U.S.C. § 47502 - Noise measurement and exposure systems and identifying land use compatible with noise exposure

## Text

After consultation with the Administrator of the Environmental Protection Agency and United States Government, State, and interstate agencies that the Secretary of Transportation considers appropriate, the Secretary shall by regulation—

(1) establish a single system of measuring noise that—

(A) has a highly reliable relationship between projected noise exposure and surveyed reactions of individuals to noise; and

(B) is applied uniformly in measuring noise at airports and the surrounding area;

(2) establish a single system for determining the exposure of individuals to noise resulting from airport operations, including noise intensity, duration, frequency, and time of occurrence; and

(3) identify land uses normally compatible with various exposures of individuals to noise.

(Pub. L. 103–272, § 1(e), July 5, 1994, 108 Stat. 1284.)
