Determination of indoor disturbance level using noise monitoring device in UMK Jeli and Pengkalan Chepa campus library

Noise pollution is one of the pollution that mostly comes from human activities which it can cause harm as well as interruption of peacefulness especially to human. As a higher-learning institution, both UMK libraries should preserve its learning environment and tranquil atmosphere so that it is not disconcerting students’ concentration. For this reason, a study was conducted for three months (May, June, and July, 2016) in UMK library by measuring the noise pollution level. This study was accomplished by analyze noise level and identify the sources that cause noisiness. The noise level was taken at three different time that is in the morning, evening and at night to see the difference of noise level between those time. It was found that the noise level in both libraries is different based on time. The highest noise level was in UMKPC library as all the average sound level recorded was exceeding the standard stated by WHO. The mean sound level recorded in May was the highest (51.92 dB (A)), followed by June (49.16 dB (A)) and July (34.32 dB (A)) for both libraries. It shows that the noise level in UMKPC library was exceeded as it always exceeding the noise level stated by
WHO. The study also showed that there was a significantly difference data which the value calculated (0.00) was below than the p-value < 0.05. The major factor causing this noise pollution is the space provided in both UMK libraries. A few methods to boost this study were suggested so that it can be carried out to get preferable situation especially for UMK students.
