Intermittent Traffic

A wide open road with space for everyone, and miles upon miles of green lined roadway to let the sweet sound of speeding cars pass you by. It's uncanny the way the soft whooshes of passing traffic can lull one into a restful, almost hypnotic state. How objects moving very quickly and noisily can make you feel very still and quiet. Traffic noise, which began to be studied in the USA in the 1960's, contributes more to environmental noise exposure than any other noise source. Since then, demand for detailed analysis has soared, and policy makers began to look to acoustical scientists for answers regarding the planning of new roadways and the design of noise mitigation.
