A state-of-the-art review of measurement techniques on tire-pavement interaction noise

Modern research on tire-pavement interaction noise (TPIN) started approximately in the mid-1970s as engines became less noisy and the aerodynamic design of vehicle bodies was optimized. Currently, TPIN dominates for passenger vehicles above 40 km/h, and 70 km/h for trucks. There are a number of different measurement techniques to quantify TPIN. In this study, the measurement techniques were reviewed and divided into three categories based on the test environment: roadside, on-board, and lab. The measurement techniques have evolved from simple overall sound pressure level tests to more accurate on-board sound intensity tests, and then to sound field holography in the lab. For each technique, the equipment used, measurement setup and standard if available, measured parameters and data processing, sound field category and major noise source, and advantages/disadvantages were discussed. Finally, suggestions on the selection of measurement techniques were given.
