Room shape and size estimation using directional impulse response measurements

2002-09-20
Impulse response of a room carries abstract information on the size and shape of that room. Acoustics research has focused on obtaining reflectograms from these physical characteristics using acoustical modelling techniques. However, estimation of the physical structure is also possible by analyzing the impulse responses for early reflections, echo amplitudes, arrival times and reverberation time. This paper proposes a new method to estimate the physical structure of a room using the features of directional impulse response (DIR) measurements obtained by applying the MLS-technique with a directional loudspeaker and a soundfield microphone. The results for 4 rooms were also displayed.
