This study evaluates the performance of three theoretical models for correcting dynamic pressure affected by tube length. The experiments involved measuring sinusoidal pressure waves with varying frequency bandwidths, using tubing systems ranging from 20 cm to 300 cm in length including multiple tubing systems connecting three or more tubes. The results showed that the Bergh and Tijdeman models, with constant and variable polytropic parameters respectively, had superior correction performance for various tube lengths, while the Whitmore & Leondes model showed discrepancies. The Bergh & Tijdeman model, with a polytropic parameter of 1.4, is recommended due to its convenience and accuracy. Furthermore, including the inner volume of the pressure transducer in the theoretical model was found to be crucial for accurate correction, as not doing so caused significant errors. The Bergh & Tijdeman model was also found to efficiently correct tube length effects in multiple tubing systems, eliminating the need for time-consuming and laborious experiments.
