This work is aimed at the problem of continuously measuring and predicting the impulse response within a reverberant room using sources-of-opportunity. The target application is that of compensating a sound reproduction system for variations in room acoustics and the non-ideal placement of the loudspeakers. The prediction of the impulse responses corresponding to the locations of an arbitrary number of listeners requires knowledge of the room geometry and the acoustic impedance of the boundaries. The room geometry may be obtained by estimating the image locations of a source. This has been addressed by the use of small arrays, with novel geometry, and processing both angular and temporal measurements. Preliminary practical results are presented and compared to theoretical predictions.
