Research on Sound Velocity Measurement Method by Three Microphones Based on LABVIEW

Abstract:

This paper proposes a new method of getting sound velocity by measuring the sound pressure at three positions in a tube. By using LabVIEW software as a platform and building the measurement system, sound velocity at different frequencies in current media is measured. Compared the experimental results with theoretical calculation ones, the correctness of the method discussed in this paper and the reliability of the system are validated.
