Abstract

The aim of this research was to map the noise level. The survey method with a questionnaire for 30 respondents taken at random was used to obtain data on effects on the academic atmosphere during the period August - October 2019. Measurement noise levels based on Equivalent Continuous Noise Level Data during the day (L_S), night (L_M) and one-day (L_SM). This data is collected from 256 coordinates by a digital sound level meter and two application software. Mapping using the Surfer application ver11, results show that the noise level catagory into 5 areas: (1) Red zone, 75-80 dB(A); (2) Yellow zone, 65-75 dB(A); (3) Green zone, 55-65 dB(A); (4) Dark blue zone, 50-55 dB(A); and (5) the blue/bright zone, 45-50 dB(A). Noise levels in near or inside building and students gather is close to the threshold. At near to highways, canteen and near housing, open space and parking area indicate that exceed the threshold of 55 dB (A) and 33.1% of students feel disturbed when the noise level is at 61 + 3 dB(A). As a result, to improve the academic atmosphere, the area near the highway built physical barriers or tree planting and manage the parking area better.
