The Influence of Excitation Type on Reverberation Time Measurements

The goal of this paper is to compare the results of reverberation time measurements obtained with different sound sources (both loudspeakers and other types of excitation) using the impulse response measurement method. Loudspeakers of different directivity and size were used (including a subwoofer) in order to determine the possible influence of these properties on the results of measurements. Other types of excitation were inflated balloons of different sizes, pistol shots, firecrackers, hand claps etc. The spectral content and the obtained sound pressure level of each source were investigated in order to find the limits of the source itself.
