摘要

摘要电动汽车正在逐步进入当前嘈杂的城市生态系统。尽管电动汽车显然比传统的内燃机车（ICEV）更安静，但它们会对噪音图产生影响，路面设计师在设计未来的低噪音路面时应考虑到这一点。因此，本研究的主要目的是确定道路路面设计师应考虑的最重要方面。因此，本文分析了电动汽车发出的噪音，考虑了参数（如速度和频率）和比较，以确定关键特性。结果表明，电动汽车噪声由于采用了声车报警系统（AVAS）、高频峰值和噪声振动的严重性，需要改进路面声学设计。

Electric vehicles diffusion: changing pavement acoustic design?

Abstract Electric vehicles (EVs) are progressively entering into the current noisy urban ecosystem. Even though EVs are apparently quieter than traditional Internal Combustion Engine Vehicles (ICEVs), they have an impact on noise maps and road pavement designers should take this into consideration when designing future low-noise road pavements. Consequently, the main objective of this study is to define what are the most important aspects that road pavement designers should take into account. For this reason, in this paper, the noise emitted by EVs was analysed, considering parameters (e.g., speed and frequency) and comparisons, in order to identify crucial characteristics. Results show that EV noise could call for the improvement of pavement acoustic design due to the Acoustic Vehicle Alerting System (AVAS), high-frequency peaks, and noise vibration harshness.

期刊介绍： Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
