Abstract:Death Valley National Park provided an environment that allowed a demonstration of
quieter pavement use. Sound measurements near the tire-pavement interface, near the
road, and in areas of frequent human use were conducted and analyses performed in order
to determine the general sound environment in the park and the potential benefit of
using quieter pavements. Tire-pavement noise data were collected using the on-board
sound intensity (OBSI) methodology, where sound levels for 15+ locations were
identified. The OBSI levels for specific pavements in Death Valley were then used in a
special research version of the FHWA Traffic Noise Model® (TNM®) in order to predict the
potential effect of using quieter pavements at the park.
