San Francisco Noise Map

Traffic is the single greatest contributor to ambient noise levels in San Francisco. Streets with high volumes of trucks and busses are heavily impacted by elevated ambient noise. The acoustical energy in a heavy truck is often twenty times greater than that of a personal automobile. Elevated traffic volumes expose residents that live near highways and arterial streets to the highest noise levels in San Francisco and also to air pollutants that are associated with traffic.
