Zusammenfassung:	Method for monitoring a small-diameter conduit, of the nozzle type, characterised in that air or other gas is blown at one end of the conduit (11) and in that, at the other end of the conduit (18), the intensity of the sound, especially of ultrasound, is measured at the exit of the conduit and then the sound level is converted (19) into an electrical signal, the conduit then being judged acceptable when the electrical signal lies between two specified values.
