Noise Contours

See the most recent noise contours for MHR.

The Sacramento County Department of Airports periodically conducts noise studies to assess the noise impacts of aircraft operations. The need to conduct a noise study is generally prompted by a significant change in aircraft operations--either the number of operations conducted at the airfield, the number and type of aircraft using the airfield or the flight paths used for airfield departure/arrival changes.

Calculated noise contours do not represent exact measurements. Noise levels inside a contour may be similar to those outside a contour line.
