Increase the Threshold of Hearing on Offshore Workers of PT. X in Pabelokan Area

Abstract

In general the increase auditory threshold frequency audiometric screening starts at 4000 Hz and then expanded in the surrounding frequencies used for conversation. The threshold of hearing is the lowest sound that can still be heard. The higher the value of the threshold of hearing, then power is heard increasingly declining. The effects of noise on hearing loss initially temporary and recovery occurs quickly after exposed by noise. A person exposed to noise is constantly losing power hear who settled and cannot be recovered. Inspection results that PT X workers audiometric in June 2001 until June 2002 showed 148 from 960 workers still experience decreased hearing and 70 people which shows the characteristics of NIHL. This study aims to analyze the factors associated with the increase in the threshold of hearing the offshore workers of PT. X in Pabelokan Island, Kepulauan Seribu, Jakarta. This research is quantitative research with cross sectional design research and carried out from October to December 2014. The results showed that all the variables examined have a relationship with the increase in the threshold of hearing of workers (aged, r = 0.001; body mass index, r = 0.000; metabolic disease history, r = 0.000; working period, r = 0.000; smoking habit, r = 0,022).
