摘　　要：一般在公路上进行CPX轮胎/路面噪音测量时,环境温度对测量的影响往往是不易受控制的。研究人员们已针对此问题开发出一温度修正方法,透过不同的温度参数以补偿温度对量度得出的噪音水平之影响。本研究试图以一整天的CPX测量结果,以探索测试时使用环境气温和路面温度为本的修正及其可靠性,同时并得出两种路面上的温度修正值。Tyre/road noise measurement on public roads is often influenced by the uncontrollable environmental parameter of temperature. Researchers worldwide have developed a method called temperature correction to compensate its effect on the measured noise level with different temperature descriptors. This study attempts to explore the reliability of correction using air and road surface temperatures with a one-day test. Temperature constants for two road surface types are yielded.
