Abstract

Low frequency noise (20 - 200 Hz) from combustion engines typically dominates the indoor sound environments and is a source for annoyance and sleep disturbance. This study investigated the impact on low frequency noise when diesel operated buses were replaced by electric buses along a bus line in Gothenburg, Sweden. Noise measurements were performed indoors and outdoors for a selection of apartments directly exposed to bus traffic as well as for reference apartments, before and after the intervention. In addition, noise levels were calculated. The results show a significant reduction of the indoor low frequency noise in the range 40 - 80 Hz in the apartments directly exposed to passing buses, both during bus passages (on average 10 dB), and in one-hour measurements (on average 5 dB). The results further show that A-weighted values fail to accurately represent the reduction in noise achieved by the intervention.

用电动巴士取代柴油巴士，减少了住宅低频噪音

内燃机产生的低频噪声（20 - 200 赫兹）通常在室内声环境中占主导地位，是造成烦扰和睡眠障碍的原因之一。本研究调查了瑞典哥德堡一条公交线路上的柴油公交车被电动公交车取代后对低频噪声的影响。在干预之前和之后，对一些直接暴露于公交车交通的公寓以及参考公寓进行了室内和室外噪声测量。此外，还计算了噪音水平。结果表明，在直接暴露于过往公交车的公寓中，40 - 80 Hz 范围内的室内低频噪音明显降低，无论是在公交车经过时（平均降低 10 分贝），还是在一小时的测量中（平均降低 5 分贝）。结果进一步表明，A 加权值不能准确反映干预措施所取得的降噪效果。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
