Noise is a sound pollution which is at the certain level becomes a stressor that has an impact on changes in physiological functions and behavior. Stress caused by repetitive noise results in disruption of homeostasis and changes in individual behavior. The purpose of this study was to analyze changes in the behavior of mice when exposed to noise with different durations of time and to compare the behavior of mice after exposure to noise through an open field test. A total of 21 male mice were divided into three treatment groups that exposure to 95 dB traffic noise for (1) 0 minutes (as control, K), (2) 90 minutes (Pa treatment), and (3) 150 minutes (treatment Pb). Each group consisted of 7 mice which were kept 2-3 in one cage. The treatment lasted for three days after three days of acclimatization. During noise exposure, behavioral observations were made in the cage 3 times every 10 minutes in the beginning, 10 minutes in the middle, and 10 minutes in the end. The behaviors observed were eating, drinking, grooming, foraging, locomotion, resting, social behavior, fighting, exploration, and nest building. After noise exposure, an open field test was continued for 5 minutes with 3 repetitions and observation parameters such as duration of movement, time spent in the inner zone, and amount of feces. The results showed that the treatment group had higher resting and fighting behavior than the control (p<0.05), while locomotion, social, and exploration behaviors were lower than the control (p<0.05). The feeding and grooming behavior in the Pa group was higher, but the Pb group was lower than the control group (p<0.05). The results of the open field test showed that the treatment group gave the lower duration of movement and spent time in the inner zone compared to the control (p<0.05), while the number of feces, although increased, the results of the statistical test were not significant. All results of noise exposure treatment showed an impact on changes in the behavior of mice. It can be concluded that a long duration of noise increases rest and fighting behavior; reduce locomotion, social, and exploratory behavior; as well as both decrease or increase feeding and grooming behavior. In addition, the long duration of the noise can also reduce the duration of movement and spent time in the inner zone in the open field test.
