The Study of Noise and Noise Contour Mapping at The Area in Front of Ubon Ratchathani University

Abstract

          This study aims to study the level of noise from 6 stations of cabaret sources and 28 monitoring stations surrounding cabaret area in front of Ubon Ratchathani University. Measurements both in normal days and holidays. Then analyze the results by compared to the standard. To map the noise contour in front of Ubon Ratchathani University by using computer program NM Plot. The results showed that the noise from the source has exceeded 90 decibels(A) in 3 cabarets. Which noise levels ranged from 90.6 to 96.6 decibels(A). The measurement at the monitoring stations surrounding cabaret area found that noise levels were below the standards with levels in between 51.7 - 80.9 decibels(A). For the Noise contour mapping, it was found that the vocal lines in front of Ubon Ratchathani University range in between 55.0 - 72.9 decibels (A) during normal days and 60.0 - 75.0 decibels (A) during the holidays. Therefore, the relevant authorities should be monitored and controlled the noise level. Especially from the cabaret source in front of Ubon Ratchathani University. Which is a source of noise that causes an annoyance to the community.
