Abstract
Background: The damaging effect of noise on vestibular disturbance is well known, first described in 1890 by Haberman in tinkers with occupational hearing loss. Others have reported vestibular disturbances and abnormalities, such as balance disorders, dizziness, vertigo, and even spontaneous nystagmus in workers exposed to various kinds of occupational noise. Objective: To evaluate vestibular function in subjects with chronic noise exposure. Subjects and methods: Eighty subjects were included in the study, divided into 2 groups: 60 subjects exposed to noise in laundry with mean age 41.53±11.15 (study group) and 20 subjects not exposed to noise with mean age 38.60±6.48 (Control group). All subjects underwent audiovestibular evaluations (puretone audiometry, tympanometry, vedionystagmography, and posturography). Results: This study demonstrated elevated hearing threshold at audiometric frequencies 2-8 KHz (pv <0.001) and speech discrimination (pv <0.001). in addition, marked caloric weakness and reduced SOT composite scores (pv = <0.001), reduced SOT equilibrium scores in noise exposure subjects (pv<0.001), reduced SOT sensory scores in VEST and PREF (Pv <0.001). Furthermore, there was a positive correlation between duration of exposure and auditory and vestibular implications. Conclusion: this study revealed apparent effect of noise on auditory and vestibular system.
