Abstract

The present study aims to investigate the noise level on hospital area in Makassar City, Indonesia, particularly in Hasanuddin University Hospital, and Wahidin Sudiro Husodo Hospital, a public hospital, which located in Tamalarea District in the city, and both hospital is situated neighbored each other. Further, the study attempt to develop a spatial mapping of the noise levels in both hospital areas. The present study conducted noise level measurement at 43 observation points in the area. Determination of the measurement points utilized GPS Tracker Lite application by using the latitude and longitude on Google Earth. The noise level measurement conducted for 10 minutes using an SLM-type TM-103. The spatial mapping of the noise level used a spatial mapping application, namely Surfer 7.0. The investigation results obtained noise level ranges from 55.7 dB to 82.6 dB. Further, the value of the noise level at the observation point located in the hospital area is 60.1 dB, and the location of the parking spot that is 66.4 dB. Additionally, the noise level of the observation point located on the side of the road is 74.1 dB. Generally, the noise levels exceeded the noise level of quality standards in the area of the hospital that is 55 dB. The results obtained by the dominant noise level mapping for the yellow color noise levels between 60-72 dB which is in the hospital building.
