Noise exposure in a hospital is known to have considerable impact not only to the healthy workers, but affects the ability for speedy recovery to the patients as well. However, recent investigations showed that the noise emission in a hospital tends to increase from year to year, for example John Hopkins Hospital. Dr. Soetomo General Hospital is the largest hospital in eastern part of Indonesia serving 2,500 outpatients and 1,500 inpatients per day as of January 2017, tripled from 2014. This also implies that the activities also increase significantly, from supporting services such as laundry to clinical services. In this paper, we present our recent study on the noise emission focusing on the supporting activities of the hospital such as water pump station, boiler, central kitchen, incinerator and workshop. The aim is to investigate the noise dose exposure to the workers of each supporting facility. We measured the noise emission level of the facility during its respective working hours. The results showed that all the facilities emitted higher level (in decibel) than allowed by the WHO. For the continuous noise, the average noise level for the water pump station was about 89.3 dB(A) and the workers were exposed almost 100 times more than that of the allowed noise exposure daily dose. The crushers at the incinerator facility were the highest of all intermittent noise sources at 98.4 dB(A). Furthermore, the noise level difference between outside and inside the water pump station was only reduced 1 dB, which suggests that either the sound enclosures was no longer effective. To summarize, the overall results showed that either the continuous or intermittent noise source the workers were exposed to high dose of noise daily.
