Abstract: A method for estimating the sensitivity in an environment of a sound emission detector device capable of detecting a physical phenomenon producing a spatially limited sound emission, said detector device comprising a transducer array, said method comprising a) receiving at least one signal from at least one respective transducer of the transducer array, said array being place within said environment, b) estimating from the at least one signal received at step a) a detection threshold value of a spatially limited source sound emission parameter, c) estimating from the detection threshold value estimated at step b) a quantity representative of a magnitude of the physical phenomenon, d) displaying the quantity estimated at step c) so as to inform the user of the sensitivity of the detector.

Abstract: A method and apparatus for checking an enclosure for leaks. An ultrasonic signal generator on one side of the enclosure emits ultrasonic signals. An array of ultrasonic transducers on the other side of the enclosure received ultrasonic signals from the signal generator through a leak and produces an acoustic image. An optical camera generates an optical image that may be combined with the acoustic image to display the location of a leak in the enclosure. An estimate of the leak size may be calculated and displayed together with the acoustic image.
