摘要

轮胎正在成为道路车辆，尤其是电动汽车的主要噪声源。特别是重型货车，在这种轮胎噪音中可以听到音调。本研究旨在评估在静音发动机车辆（如电动汽车）的情况下，音调和声压级对当地居民烦恼的相对影响。48人受到四种声音条件的影响，根据两因素实验设计（调性和最大声压级），代表城市高速公路的交通噪音。结果表明，听觉音调成分的存在导致烦恼的增加相当于12 dB(a)的水平增加，远远超出了通常适用的惩罚。对参与者感到的疲劳也有较小的影响。这些结果支持修改轮胎外部噪音规定（该规定只控制最大声压级），以考虑可能的可听到的音调。

Relative influence of maximum sound pressure level and tonality of truck tire noise on annoyance for local residents

Tires are becoming the main source of noise from road vehicles, especially for electric vehicles. Especially in the case of heavy goods vehicles, tones can be heard in this tire noise. This study aimed to evaluate the relative influence of tonality and sound pressure level on the annoyance of local residents, in the case of silent engine vehicles (e.g. electric vehicles). Forty-eight people were subjected to four sound conditions varying according to a two-factor experimental design (tonality and maximum sound pressure level) and representing the traffic noise of an urban motorway. Results showed that the presence of an audible tonal component leads to an increase in annoyance equivalent to that of a 12 dB(A) increase in level, well beyond the penalties usually applied. There was also a smaller effect on the fatigue felt by the participants. These results argue in favour of amending tire exterior noise regulations (which only control the maximum sound pressure level), to take account of possible audible tones.

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.
