Abstract

In 2009, the European Union (EU) introduced a directive governing the labelling of tyres, which underwent revision in 2020. This labelling system encompasses three key parameters related to tyre performance: wet grip (safety), rolling resistance (energy consumption), and external rolling noise (environmental impact). These label values serve as crucial information for customers seeking to purchase replacement tyres for their vehicles.

However, the accuracy and reliability of noise measurements have been a concern. Testing conducted across various ISO-standardized tracks has revealed significant inconsistencies in noise levels, with variations of 4–5 dB between tracks. Such discrepancies directly impact the labelling process, introducing uncertainty.

This paper presents results of tyre noise measurements conducted on a limited number of ISO test tracks and proposes a methodology to mitigate track-to-track variability. The study exclusively focuses on passenger car tyres. By addressing these inconsistencies, this research aims to enhance the accuracy and reliability of tyre noise labelling, thereby facilitating informed consumer decision-making and promoting environmental sustainability.

ISO 测试轨道对欧盟轮胎标签噪音值的影响

2009 年，欧盟（EU）出台了一项关于轮胎标签的指令，并于 2020 年进行了修订。该标签系统包括与轮胎性能有关的三个关键参数：湿地抓地力（安全）、滚动阻力（能耗）和外部滚动噪音（环境影响）。这些标签值是客户为其车辆购买替换轮胎的关键信息。然而，噪声测量的准确性和可靠性一直是个问题。然而，噪声测量的准确性和可靠性一直是个问题。在各种 ISO 标准轨道上进行的测试表明，噪声水平存在明显的不一致性，轨道之间的差异可达 4-5 分贝。本文介绍了在数量有限的 ISO 测试轨道上进行的轮胎噪声测量结果，并提出了一种方法来减少轨道间的差异。该研究专门针对乘用车轮胎。通过解决这些不一致性，本研究旨在提高轮胎噪声标签的准确性和可靠性，从而帮助消费者做出明智的决策，促进环境的可持续发展。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
