| Summary: | Noisy work environment is a physical factor that can cause health
problems such as hearing loss (auditory) and extrauditory such as psychological
stress, fatigue. Noisy in a long time and can lead to a continuous decrease in
hearing, and a factor of psychological and physical stressors that can affect
auditory function, physiology, and blood pressure. Noisy stimulation through the
sympathetic nervous mechanisms can lead to higher blood pressure by increasing
total peripheral resistance and cardiac output, with repeated exposure and may
continue to accelerate the development of peripheral vascular changes in vascular
structure so that it can increase blood pressure. Objective The porpose of this
research is to determine the correlation of blood pressure with a threshold of
hearing convection factory workers.
The study design was cross-sectional. Samples were taken from the
workers of PT. MTG Yogyakarta exposed to 77 dB noise machine. Furthermore,
the worker checked with audiometric hearing threshold of pure tone and blood
pressure measurements. Data analysis using statistical test used was the Pearson
correlation test if normally distributed data, whereas Spearman's correlation test, if
the data are not normally distributed. Degree of confidence that is used in the
study was 95 %, with a significance level of 5% (p < 0,05). Based on the
correlation results showed that there was a positive relationship with the strength
of the relationship between Mean Atreal Pressure (MAP) with a lower threshold
of hearing air conduction at a frequency of 125 Hz right or left ear, 250 Hz right
or left ear, right ear 4000 Hz, 6000 Hz right ear or the left, as well as 8000 Hz in
the left ear and 4000 Hz right bone conduction garment factory workers. Intensity
noise on the measurement of the frequency of 125 Hz, 250 Hz, 4000 Hz, 6000 Hz,
and 8000 Hz was 26 - 40 dB.
Conclusion: there is a correlation between blood pressure with a threshold
of hearing on convection factory workers in Yogyakarta. |
