Calibrator for acoustic cameras and other related applications

A system for calibrating sound reception of an acoustic camera, wherein the system comprises an acoustic camera and a calibrating device, the calibration device comprising:

• a loudspeaker comprising a sound source, wherein output sound is directionally alignable;
• at least one light source, wherein light is directionally alignable, and wherein the sound source and the at least one light source is located on a same side of the calibration device, aligned output sound and aligned light propagating substantially at a same direction during calibration;
• the acoustic camera comprising:
• a screen,
• a processor,
• a handle or a fixed platform for fixed placement in a desired location, and
• a plurality of microphones;
• wherein the system is configured to:
• receive acoustic signals using said plurality of microphones, process said received acoustic signals and present a visualization of sources of said sound signals on said screen,
• present instructions to a user on the screen of the acoustic camera for manually setting a location and alignment angle of the acoustic camera,
• present a dedicated area on the screen of the acoustic camera for the light source,
• present a volume range in view of received sound levels on the screen of the acoustic camera, and
• when the light source is substantially in the dedicated area and the received sound level stays in a desired sound level range, the acoustic camera is configured to be calibrated.
