Abstract


This paper aimed to validate the experimental result of reverberation time using balloon burst method with the model (sabine equation) using AcMus software. The experimental procedure utilized dynamic microphone as the receiver, balloon as the sound source and AUDACITY software to record and analyze the impulse created upon popping the balloon. Balloon Burst method has a reverberation time value of 1.28s while the AcMus software gave a reverberation time value of 1.33s. The percent error was calculated and showed a 3.76% error. Hence, the balloon burst method can be used to determine the reverberation time of a classroom also, it can be utilized as instructional materials in science classes.

Author Keywords: Balloon burst method, reverberation time, Audacity, AcMus and dynamic microphone.
