Standard Method of Test for Measurement of Tire/Pavement Noise Using the On-Board Sound Intensity (OBSI) Method
用车载声强(OBSI)法测量轮胎/路面噪声的标准试验方法
AASHTO T 360-16(2020)描述了使用车载声强(OBSI)方法测量轮胎/路面噪声的程序以及测量系统的验证程序。该测试方法提供了轮胎/路面界面附近点单位面积声功率的客观测量值。本文描述的OBSI测量方法允许在与其他噪声源隔离的情况下测量轮胎/路面噪声,从而可以比较路面的噪声性能。原AASHTO临时标准TP 76。
2016年首次作为完整标准发布。
AASHTO T 360-16 (2020) 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.Formerly AASHTO Provisional Standard TP 76. First published as a full standard in 2016.
