However, there still is a lack of experimental studies regarding the interior noise and vibration of metro vehicles. Therefore, overnight field experiments of the interior noise and vibration of a standard B-type metro train running on a viaduct were conducted on metro line 14 of Guangzhou (China). Both the A-weighted sound pressure level and linear sound pressure level were used to evaluate the interior noise signals in order to revel the underestimation of the low-frequency noise components. The results show that the interior noise concentrates in the low-to-middle frequency range. Increasing train speeds have significant effects on the sound pressure level inside the vehicle. However, two obvious frequency ranges (125\u2013250 Hz and 400\u20131000 Hz) with respective corresponding center frequencies (160 Hz and 800 Hz) of the interior noise are nearly independent of train speed. The spectrum analysis of the vehicle body vibration shows that the frequency peak of the floor corresponds to the first frequency peak of the interior noise spectrum. There are two frequency peaks around 40 Hz and 160 Hz of the sidewall\u2019s acceleration level. The frequency peaks of the acceleration level are also independent of the train speeds. It hopes that the field measurements in this paper can provide a data set for researchers for further investigations and can contribute to the countermeasures for reducing interior noise and vibration of a metro vehicle.<\/jats:p>","DOI":"10.3390\/ijerph17082807","type":"journal-article","created":{"date-parts":[[2020,4,21]],"date-time":"2020-04-21T04:49:38Z","timestamp":1587444578000},"page":"2807","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Field Study of the Interior Noise and Vibration of a Metro Vehicle Running on a Viaduct: A Case Study in Guangzhou"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3688-8673","authenticated-orcid":false,"given":"Lei","family":"Yan","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"},{"name":"National Engineering Laboratory for High Speed Railway Construction, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhou","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunfeng","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"},{"name":"National Engineering Laboratory for High Speed Railway Construction, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2746-182X","authenticated-orcid":false,"given":"Xuhui","family":"He","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"},{"name":"National Engineering Laboratory for High Speed Railway Construction, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenzhi","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"},{"name":"National Engineering Laboratory for High Speed Railway Construction, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kehui","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojie","family":"Zhu","sequence":"additional","affiliation":[{"name":"Guangzhou Metro Corporation, Ltd., Guangzhou 510000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,19]]},"reference":[{"key":"ref_1","unstructured":"China Urban Rail Transit Association (2019).
