Calculations also realized by applying formula LAeq (10 minutes) and Leq (afternoon), to get the standard limit noise of the area. The results showed that the response of people feel comfortably in the range of 55 to 60 dBA. These values may reach of 20% higher than as mentioned in the standard noise level in Indonesia (Kep-48/Menlh/11/1996).
