Review of the air pollution from the perspective of sound comfort in the coastal space. Case study of the Boboca Monument, Manado City

Abstract

Continuous exposure to an area with a sound above the threshold level is one of the triggers for noise pollution in public spaces. Public spaces are spaces where people of all ages gather for leisure activities, recreation, etc. The purpose of this study was to find the average dBA value of noise, community perceptions regarding the comfort of sound in coastal public spaces, and the relationship between the dBA value and the existing sound comfort standards. The focus of this research is to contribute to a public space that is free from noise pollution. The study was conducted on the coast of Manado, precisely in the Boboca monument area, using mixed methods through the formula LAeq 10 minutes and Leq daylight to get the standard value of noise. The results found noise numbers in the range 77.4 – 80.2 dBA, this value has exceeded the required standard of 50 dBA, and the results of the perception are also supportive, which is dominant in public perception. It means that coastal public spaces in the Boboca monument area have been exposed to noise pollution
