This cross-sectional study assessed the extent of noise exposure and its influence on hearing capabilities among quarry workers in Ashanti region.<jats:italic>Methods<\/jats:italic>. The study involved 400 workers randomly selected from five quarries in Ashanti region from April to June 2012. Data was collected using structured questionnaires, physical examination, and audiological assessments. A logistic regression model was fitted to assess independent predictors of hearing loss.<jats:italic>Results<\/jats:italic>. All the machines used at the various quarries produced noise that exceeded the minimum threshold with levels ranging from 85.5\u2009dBA to 102.7\u2009dBA. 176 (44%) of study respondents had hearing threshold higher than 25\u2009dBA. 18% and 2% of these were moderately (41\u201355\u2009dBA) and severely (71\u201390\u2009dBA) impaired, respectively. Age, duration of work, and use of earplugs independently predicted the development of hearing loss. Use of earplugs showed a protective effect on the development of hearing loss (OR = 0.45; 95% CI = 0.25, 0.84).<jats:italic>Conclusion.<\/jats:italic>This study provides empirical evidence on the extent of damage caused to quarry workers as a result of excessive noise exposure. This will support the institution of appropriate protective measures to minimize this threat.<\/jats:p>","DOI":"10.1155\/2016\/7054276","type":"journal-article","created":{"date-parts":[[2016,1,21]],"date-time":"2016-01-21T21:03:20Z","timestamp":1453410200000},"page":"1-7","source":"Crossref","is-referenced-by-count":16,"title":["Noise Exposure and Hearing Capabilities of Quarry Workers in Ghana: A Cross-Sectional Study"],"prefix":"10.1155","volume":"2016","author":[{"given":"Charles Kwame R.","family":"Gyamfi","sequence":"first","affiliation":[{"name":"Center for Disability and Rehabilitation Studies, Department of Community Health, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isaac","family":"Amankwaa","sequence":"additional","affiliation":[{"name":"Department of Nursing, Garden City University College, Kumasi, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Owusu Sekyere","sequence":"additional","affiliation":[{"name":"Department of Interdisciplinary Studies, University of Education, Kumasi, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Boateng","sequence":"additional","affiliation":[{"name":"Department of Community Health, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"issue":"11","key":"2","first-page":"2627","volume":"57","year":"1998","journal-title":"American Family Physician"},{"key":"3","first-page":"1651","volume-title":"Selected occupational risk factors","year":"2004"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.5001\/omj.2013.96"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.4314\/ajhs.v11i1.30778"},{"issue":"1","key":"7","first-page":"14","volume":"2","year":"1992","journal-title":"African Newsletter on Occupational Health and Safety"},{"key":"9","volume-title":"Standards and regulations","year":"2000"},{"key":"10","year":"2001"},{"issue":"1-2","key":"11","first-page":"91","volume":"9","year":"2002","journal-title":"African Journal of Health Sciences"},{"key":"12","year":"2003"},{"key":"13","first-page":"262","volume":"7","year":"1965","journal-title":"ASHA"},{"key":"14","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1288\/00005537-194511000-00002","volume":"55","year":"1945","journal-title":"The Laryngoscope"},{"key":"15","year":"2013"},{"key":"16","doi-asserted-by":"crossref","first-page":"716","DOI":"10.1109\/TAC.1974.1100705","volume":"19","year":"1974","journal-title":"IEEE Transactions on Automatic Control"},{"key":"17","series-title":"edited by: B.
