# §47502. Noise measurement and exposure systems and identifying land use compatible with noise exposure


After consultation with the Administrator of the Environmental Protection Agency and [United States](/usc/49/40102.md?p=a-46) 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](/usc/49/47501.md?p=1) and the surrounding area;
- (2) establish a single system for determining the exposure of individuals to noise resulting from [airport](/usc/49/47501.md?p=1) operations, including noise intensity, duration, frequency, and time of occurrence; and
- (3) identify land uses normally compatible with various exposures of individuals to noise.
