Abstract: A device is provided for checking a probe for measuring the pressure of a flow, the probe comprising an internal volume and at least one orifice communicating with the outside of the volume. The device comprises: an acoustic transmitter and an acoustic receiver; connection means to connect the device to the probe, such that the transmitter transmits an acoustic signal propagated in the internal volume, and such that the receiver picks up an acoustic signal observed in the internal volume; processing means suitable for comparing the observed signal to a reference signal. The connection means are configured in such a way that an incorrect connection of the probe disturbs the propagation in the internal volume of an acoustic signal transmitted by the transmitter. The processing means are configured to detect an incorrect connection of the probe by comparing the acoustic signal observed in the internal volume with the reference signal.

Abstract: The present invention relates to a device for generating sound messages, comprising:



a generation chain configured to generate a first and a second sound signal carrying a useful audio signal and a test audio signal;
a conversion chain configured to transform the first and second sound signals into first and second analog signals; and
a verification chain configured to extract the test audio signal from a combination of the analog signals to verify the integrity of the useful audio signal.




The first sound signal corresponds to the sum of the test audio signal and the useful audio signal, and the second sound signal corresponds to the sum of the test audio signal and an opposite signal corresponding to the opposite of the useful audio signal.

Abstract: A method for detecting the blocking of a drain hole of a pressure measurement probe by means of an acoustic checking device, the probe comprising an internal volume provided with at least one drain hole communicating with the outside of the volume, the checking device being able to be connected to the internal volume of the probe and comprising means for measuring an acoustic imprint of the internal volume. The method comprises: measuring an acoustic imprint by plugging the at least one drain hole from the outside of the volume; measuring an acoustic imprint without plugging the at least one drain hole from the outside of the volume; and comparing the two measured acoustic imprints.
