In this work, a protocol to study Tyre Cavity Noise (TCN) was developed. Using this new method, TCN was measured on 24 different road pavements, together tyre noise emission measured with the Close-Proximity (CPX) method and road texture measurements. The results were used to model the relationship between TCN and road surface parameters. The analysis shows that the Standard Reference Test Tyre’s (SRTT) TCN is correlated to megatexture at low frequencies and that the correlation between TCN and outside noise emission is significant for frequencies lower than 1 kHz. The use of sensors placed inside the tyre for monitoring the acoustic performance of road pavements presents several advantages compared to the CPX method, such as a more compact design, lower cost and lower hazards both for the instrumentation and for other vehicles.

在这项工作中，开发了研究轮胎空腔噪声 (TCN) 的协议。使用这种新方法，在 24 条不同的道路路面上测量了 TCN，同时测量了使用近距离 (CPX) 方法测量的轮胎噪声排放和道路纹理测量。结果用于模拟TCN与路面参数之间的关系。分析表明，标准参考测试轮胎 (SRTT) 的 TCN 与低频下的大纹理相关，并且 TCN 与外部噪声发射之间的相关性对于低于 1 kHz 的频率非常重要。与 CPX 方法相比，使用放置在轮胎内部的传感器来监测道路路面的声学性能有几个优点，例如设计更紧凑、成本更低，并且对仪表和其他车辆的危害也更低。
