AASHTO TP 76 2015 Edition, January 1, 2015 Standard Method of Test for Measurement of Tire/Pavement Noise Using the On-Board Sound Intensity (OBSI) Method
More info
Description / Abstract:
This test method describes the procedures for measuring
tire/pavement noise using the on-board sound intensity (OBSI)
method and the procedures for verification of the measurement
system. The test method provides an objective measure of the
acoustic power per unit area at points near the tire/pavement
interface.
The OBSI measurement method described herein permits tire/pavement noise to be measured in isolation of other noise sources allowing the noise performance of pavements to be compared.
This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
