VEHICLE NOISE RADIATION, EFFECTIVE HEIGHT AND FREQUENCY MEASUREMENTS

Actual vehicle measurements indicate that the best single frequency approximation for "A" weighted noise is 650 Hx. For light vehicles, the effective source height is 0.2 M (0.7 feet) above the lane surface. For heavy vehicles, the effective source height is 0.8 m (2.6 feet) above the lane surface. /Author/
