| Abstract: | A new method of solving the sound velocity by measuring the sound pressure at three positions in a tube is proposed.LabVIEW software is used as a platform to build the sound velocity measurement system,sound velocity at different frequencies in current medium are measured.By comparing the experiment results with the theoretical sound velocity calculated values,the correctness of the measurement metha is validated by the experiment results. |
