Likewise, studies in humans have been suggesting that noise can damage the vestibular system, even with normal assessment results. OBJECTIVE: To assess the vestibular system of workers exposed to noise and to compare with individuals not exposed. METHODS: Twenty normal-hearing male adults were divided in the study group (SG), exposed to occupational noise, and control group (CG). We conducted the following procedures: medical history, Dizziness Handicap Inventory (DHI), Dix-Hallpike maneuver, and electronystagmography (eye and caloric tests). RESULTS: The DHI score did not differ between groups. The Dix-Hallpike maneuver was normal for both groups. All individuals had normal responses in the eye tests. 50% of the SG had hyperreflexia in the caloric tests, with a significant difference between the groups. There was a trend towards a statistical significance in the absolute values of angular speed of the slow component in the cold-air test, which were higher in the SG. There was a significant difference between the groups in the relative values of labyrinthine preponderance, which were higher in the SG. CONCLUSION: Our findings showed that 70% of the workers exposed to occupational noise had vestibular alterations identified with electronystagmography, whereas 100% of the individuals in the CG had normal results in the vestibular assessment. Moreover, only 20% of the sample in both groups had vestibular complaints, indicating the presence of subclinical vestibular changes in 50% of the individuals exposed to occupational noise.<\/jats:p>","DOI":"10.3233\/wor-211088","type":"journal-article","created":{"date-parts":[[2022,9,9]],"date-time":"2022-09-09T15:42:50Z","timestamp":1662738170000},"page":"1217-1225","source":"Crossref","is-referenced-by-count":1,"title":["Effects of noise on the vestibular system of normal-hearing workers"],"prefix":"10.1177","volume":"73","author":[{"given":"Victor Oct\u00e1vio","family":"Macena Duarte","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Speech-Language-Hearing Sciences, and Occupational Therapy, Faculty of Medicine (FMUSP), University of S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivone Ferreira","family":"Neves-Lobo","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Speech-Language-Hearing Sciences, and Occupational Therapy, Faculty of Medicine (FMUSP), University of S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandra Giannella","family":"Samelli","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Speech-Language-Hearing Sciences, and Occupational Therapy, Faculty of Medicine (FMUSP), University of S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"2","key":"10.3233\/WOR-211088_ref1","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1590\/S0034-89102009000200021","article-title":"Prevalence of auditory and vestibular symptoms among workers exposed to occupational noise","volume":"43","author":"Ogido","year":"2009","journal-title":"Rev Sa\u00fade P\u00fablica"},{"key":"10.3233\/WOR-211088_ref2","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1016\/j.heares.2016.03.002","article-title":"Effects of high intensity noise on the vestibular system in rats","volume":"335","author":"Stewart","year":"2016","journal-title":"Hear Res"},{"key":"10.3233\/WOR-211088_ref3","first-page":"19","article-title":"Sub-Clinical Effects of Chronic Noise Exposure on Vestibular System","volume":"22","author":"Viola","year":"2020","journal-title":"Transl Med UniSa"},{"key":"10.3233\/WOR-211088_ref4","doi-asserted-by":"crossref","first-page":"593919","DOI":"10.3389\/fneur.2020.593919","article-title":"Effects of Noise Exposure on the Vestibular System: A Systematic Review","volume":"11","author":"Stewart","year":"2020","journal-title":"Front Neurol"},{"issue":"2","key":"10.3233\/WOR-211088_ref5","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1152\/jn.00642.2019","article-title":"Intense noise exposure alters peripheral vestibular structures and physiology","volume":"123","author":"Stewart","year":"2020","journal-title":"J Neurophysiol"},{"issue":"6","key":"10.3233\/WOR-211088_ref6","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1159\/000087347","article-title":"Sketches of otohistory.
