A Study of Occupational exposure of noise on Hearing in Industrial workers
Hearing protectors, NIHL, Occupational Hearing loss.
The aim of this paper is to analyse the result of individuals exposed to noise levels and their effects on hearing of 54 water plant industrial workers. Conventional Audiometric frequencies were measured and standard threshold shift was calculated for each ear along with Noise induced hearing loss proforma. Subjects were subdivided into 4 groups i.e (a) 25 to 35 yrs (b) 36 to 45 yrs (c) 46 to 55 yrs (d) 56 to 60 yrs.The range of noise level of the machines was in between 80dB and 100 dB. A dip in audiometric configuration was significantly observed at 4kHz and 8kHz, highest were 51% at high frequency bilateral. Occupational permissible noise exposure limit was for 8 hour time and distance from source of noise was 3 metres. The most affected were those workers aged 36 to 55 years and exposed to noise for over 15 to 20 years. There is a high incidence of Tinnitus in the industrial workers, unilateral tinnitus is 11% and bilateral tinnitus is 28%. Among 54 subjects, only 23 subjects used earplugs and 13 subjects used earmuffs. Workers who never used earplugs and earmuffs are 18 in number due to various reasons. It is concluded that increasing work experience and age are causing severe impact on hearing causing irreversible hearing loss. Education, training and awareness for wearing hearing protective devices is crucial. Further to this, it aimed to implement Hearing Conservation Program as a control measure in prevention of NIHL. Key words: Hearing protectors, NIHL, Occupational Hearing loss.
