The report presents criteria, methods and analyses used to develop California vehicle noise emission levels. More than 3000 noise and environmental measurements were made at sixteen level road sites in California. Included were automobiles and medium and heavy trucks traveling at constant speeds between 25 and 65 mph. Microphones were located at distances of 25, 50 and 100 feet, and at heights of 5 and 10 feet.
