In the project, researchers at the John A. Volpe National Transportation Systems Center (Cambridge, MA) completed phase two of a project to measure noise created by Florida pavements at the tire-pavement interface and correlate it with roadside sound pressure levels. Phase one of the project (FDOT project BD550) focused on mechanisms of sound generation at the tire-pavement interface, development of a working trailer based system for On-Board Sound Intensity (OBSI) measurements, and evaluation of pavement properties in relation to generated sound levels. In phase two, researchers refined and finalized development of the OBSI trailer, continued developing a correlation between tire-pavement sound intensity levels and wayside sound pressure levels, tested additional pavements and developed an acoustic inventory of pavement surfaces used in Florida.
