Room equalization based on measurements with moving microphones

R. Mazur, F. Katzberg, H. Phan, A. Mertins


For enhancing the perceived quality of a sound played in a closed room, the methods of room impulse response equalization are used. For a better control of late echoes, new approaches, such as temporal masking, exploit the properties of the human auditory system. In order to allow the listener to move freely even in a small area, a whole volume has to be equalized. Traditional methods require a measurement of a huge amount of impulse responses in this volume. In this work we propose a method which allows for a greatly reduced measurement effort. Here, we employ a dynamic method for measurement of impulse responses using just one moving microphone. The reconstructed impulse responses are used to perform equalization and a simple interpolating technique allows for a equalization at the position of the listener, who can freely move inside the measured volume.
