AB  - Traditional room-equalization involves exciting one loudspeaker at a time and deconvolving the loudspeaker-room response from the recording. As the number of loudspeakers and positions increase, the time required to measure loudspeaker-room responses will increase. We presented a technique to deconvolve impulse responses after exciting all loudspeakers simultaneously [1]. This paper presents the results of our de-convolution method compared with the traditional approach in real listening environments. We will compare the results of three different stimuli we used for testing and validating our approach: 11-channel, 7-channel, and 4-channel time-shifted log-sweeps. We measured the loudspeakers in 3 different room settings: ITU standard-based listening room, reference room, and home environment. The performance results are depicted in plots comparing the true (single-channel-at-a-time) responses with the responses obtained from the proposed approach. We also present objective metrics using log spectral distortion.
