Abstract In order to realize the low-frequency sensitivity calibration of the transducer in a non-rigid tube, a sensitivity calibration method based on the correction of the reciprocity constant in the tube is proposed.Firstly, the derivation and correction of the reciprocity constant based on the non-rigid boundary conditions and the equation of acoustic pressure in the tube, and the simulation analysis of the correction of the reciprocity constant in the tube, and the correction of the reciprocity constant in the measurement frequency band are obtained; secondly, the experimental system is built to carry out the sensitivity measurement of the transducer in the tube based on the reciprocity method.The study shows that the correction of the reciprocity constant in the tube makes the sensitivity value of the reciprocal transducer closer to the sensitivity value measured by the free-field comparison method.In the frequency range from 0.5 to 4kHz, the compensated reciprocal transducer sensitivity level has a maximum undulation of -1.41dB, which greatly improves the uncorrected measurement situation and has a small error with the free field measurements, meeting the acoustic metrology requirements.The results verify the validity and accuracy of the method through comparative analysis of experiments and simulations.
