Noise Abatement

Traffic Noise is increased by heavier traffic volumes, higher speeds and a greater percentage of trucks. ITD environmental studies involving major highway improvements must analyze existing noise levels and predict future noise levels to determine noise impacts. All traffic noise studies prepared for ITD projects must adhere to procedures and requirements as established by federal law, Federal Highway Administration (FHWA) regulations, and ITD noise analysis guidelines.

Noise Forms
