Abstract
A new adaptive ldquobeamformingrdquo signal-processing algorithm is developed to locate noise-sources aboard a pass-by rail-car, using an immobile track-side microphone-array. The microphone-arraypsilas beamforming is aided by two narrowband acoustic beacons abroad the rail-car aid to track the rail-carpsilas spatial movement and thus to locate the noise-sources with respect to the rail-car. No other auxiliary hardware (e.g., no radar nor video-camera) is needed.
