ABSTRACT
Noise can be recognized as a serious health hazard and the health effects of the hazardous noise exposure are now considered to be an increasingly important communal health problem. That is why noise surveys are conducted in order to inform population centers the risks of excessive noise exposure. In the area of Barangay Bitoon, there was no record of noise survey conducted.
This study determines environmental noise levels present in different regions of Bitoon, Jaro Iloilo City. Specifically, it is to measure the mean ambient noise levels (in dBA) in three areas of Barangay Bitoon, Jaro Iloilo City namely the public market, the karaoke television bar, and along the coastal road daily for one week.
A one week survey is conducted in the three sites. In each location, the researchers recorded the ambient noise for 5 times at intervals of 3 minutes for 30 minutes starting at 6:30am, 6:00pm, and 8:00pm.
It was found out that Bitoon Marketplace had the lowest sound pressure level with 64.7 dBA, coastal roadside ranked second with 70.7 dBA, and KTV Bar yielded the highest sound pressure level at 85.8 dBA. According to International Health Standards, constant exposure to noise that are of same levels with that KTV Bar beyond 47.5 minutes will results in hearing impairments. The study suggests that people who frequent this area should avoid staying long period of time.
