Abstract
A device is provided for checking a probe for measuring the pressure of a flow, the probe comprising: an internal volume; at least one orifice communicating with the outside of the volume; an acoustic loudspeaker, comprising an enclosure and a membrane sealing an opening of the enclosure; the opening being intended to be connected to the internal volume of the probe, so that the loudspeaker transmits an acoustic signal that is propagated through the opening into the internal volume; an acoustic receiver positioned in the enclosure of the loudspeaker that makes it possible to pick up an acoustic signal originating from outside the enclosure and passing through the membrane; and means for comparing the acoustic signal observed in the enclosure to a reference acoustic signal.
