N2 - In this study discussed the analysis of acoustic parameters of measurement and simulation of loudspeaker position at Cak Durasim Surabaya. Based on ISO-3382-1 acoustic parameters that need to be analyzed are SPL distribution, RT, C50, and C80. To get these parameters result, data retrieval using Impulse Response method was done. Measurements are made in a condition without audiences. Based on the measurement results, SPL distribution was less evenly with the maximum and minimum difference reached 14 dBA. In addition, the value of RT was 1.1 s which showed the impression of a sound was less "alive". From these measurements, it was necessary to add loudspeaker to improve the SPL distribution and the value of reverberation time. Based on the simulation, the result of the SPL distribution evenly with the maximum and minimum difference of 6 dBA, C50 of 4.5 dB, and C80 of 8.2 dB. For RT there were no significant change that were 0.68 s. It means the sound impression in the room was still less "alive". Problems in the simulation result can be solved by giving certain effects of the sound system so it doesn't need to change the material composing of the room.
