NOISE EXPOSURE FROM PRIMARY AND SECONDARY SCHOOL STUDENTS: ACASE STUDY IN MALAYSIA

Environmental

Noise exposure has negatively affected the school student and may be exposed to high noise levels during their daily study. This study aims to determine the internal sources of noise exposure in the school (objective 1), to calculate the daily noise exposure from primary and secondary schools in Malaysia (objective 2). A review of relevant literature obtained; this data set contained daily activities about noise exposure in the school and sound level in decibel. Daily noise exposure was calculated through the dose equation to get the students' permissible daily exposure. We found that occupied classrooms, canteen, school bell, schoolyard, and indoor sports are the primary sources (internal) of the noise in the school. Once data had been calculated, in Primary school, we found that on Wednesday the student’s dose with extra-curriculum activities and the time-weighted average is above the action level 50% dose and 85 dBA, while the other days are normal. In both lower and secondary school noise exposure, the student’s daily dose and the time-weighted average is less than action level. So in primary school, we need to reduce the noise at the source wherever possible and also carry out regular monitoring of the noise levels to ensure they have not increased.
