On-board sound intensity measurements and results in Florida

This paper describes an investigation of on-board sound intensity (OBSI) and concurrent wayside sound levels along multiple roadway surfaces in the state of Florida. By conducting concurrent sampling of the OBSI and wayside noise not only were insights into the pavement texture noise generation at the tire/pavement interface possible but direct comparisons allowed findings on the propagation characteristics as well. Measurement values, pavement rankings, multiple findings, and preliminary statistical modeling will be shown.
