The Acoustic Camera as a Tool for Room Acoustic Optimisation (04.03)

This contribution demonstrates the Acoustic Camera as a powerful tool for room acoustic optimisation. The goal is to get a good acoustic in a room of about 17 square meters for music mixing purposes. The Acoustic Camera records the multiple room impulse responses, which are excited by bursting balloons and sinusodial sweeps. Beamforming is applied in the time and frequency domain to a 3-D model of the room. This allows the local distribution of the spatial impulse response to be visualized. Two measurement series were done: the first one in the empty room and the second one in the furnished room with several acoustic treatments. The results of the first measurements form the basis for the arrangement of the furniture. The second series of measurements was used to investigate the influence of several acoustic treatments to the acoustic behaviour of the room impulse response.
