A screening tool to assess the level of hearing impairment of drivers and a format to measure equivalent noise level inside the SLTB buses were used to collect data. Noise measurement was done using Benetech Sound Level Meter (Model DB 130).<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n With reference to the noise level inside buses, 88.4% (\n n<\/jats:italic>\n = 53) exceeded 85 dB (A), and 21.7% of buses (\n n<\/jats:italic>\n = 13) were above 90 dB (A). According to the hearing tool's hearing impairment assessment, the hearing of the majority of the study participants (84.4%,\n n<\/jats:italic>\n = 216) was not affected. The association between hearing impairment and past history of ear diseases, surgeries, or head trauma was statistically significant (\n P<\/jats:italic>\n = 0.017).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Noise level inside the SLTB buses in Ampara and Batticaloa districts exceeded the 85 dB limit prescribed under the WHO standards of occupational noise exposure. The years of service of a bus was the only factor shown a statistically significant association with the level of noise inside the bus.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ijcm.ijcm_768_21","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T06:04:21Z","timestamp":1657605861000},"page":"280-284","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Noise Level inside Sri Lanka Transport Board Buses and Hearing Impairment of Long- and Short-Distance Bus Drivers of Ampara and Batticaloa Districts, Sri Lanka"],"prefix":"10.4103","volume":"47","author":[{"given":"Suresh Kannah","family":"Shanmugarajah","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Millawage Supun","family":"Dilara Wijesinghe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R5-27-20240828","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1080\/15428119891010479","article-title":"Occupational noise exposure of operators of heavy trucks","volume":"59","author":"Seshagiri","year":"1998","journal-title":"Am Ind Hyg Assoc J"},{"key":"R6-27-20240828","first-page":"142","article-title":"Effect of noise pollution on hearing of public transport drivers in Lahore city","volume":"24","author":"Aslam","year":"2008","journal-title":"Pak J Med Sci"},{"key":"R7-27-20240828","doi-asserted-by":"crossref","first-page":"509","DOI":"10.7162\/S1809-97772012000400013","article-title":"Prevalence of noise-induced hearing loss in drivers","volume":"16","author":"Lopes","year":"2012","journal-title":"Int Arch Otorhinolaryngol"},{"key":"R12-27-20240828","doi-asserted-by":"crossref","first-page":"49","DOI":"10.4103\/1463-1741.59999","article-title":"Noise induced hearing loss risk assessment in truck drivers","volume":"12","author":"Karimi","year":"2010","journal-title":"Noise Health"},{"key":"R14-27-20240828","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1016\/j.ijsbe.2014.10.001","article-title":"Vulnerability of bus and truck drivers affected from vehicle engine noise","volume":"3","author":"Mondal","year":"2014","journal-title":"Int J Sustain Built Environ"},{"key":"R15-27-20240828","first-page":"1","article-title":"An investigation on occupational noise exposure in Kerman metropolitan bus drivers","volume":"4","author":"Nadri","year":"2012","journal-title":"Int J Occup Hyg"}],"container-title":["Indian Journal of Community Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijcm.ijcm_768_21","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T15:03:18Z","timestamp":1787756598000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijcm.ijcm_768_21"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4]]},"references-count":6,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.4103\/ijcm.ijcm_768_21","relation":{},"ISSN":["0970-0218"],"issn-type":[{"value":"0970-0218","type":"print"}],"subject":[],"published":{"date-parts":[[2022,4]]}}}
