The LabVIEW-based virtual simulation platform for the "Speed of Sound Measurement" experimentwas successfully developed． This platform incorporates interactive features such as experimental problem

discussions，practical operation videos，and a standing wave module． It simulates real-world energy losses，including losses during electro-acoustic and acoustic-electric conversions in ultrasonic transducers，as well aspropagation losses of sound waves in the medium．Users can select the medium type (e．g．，air，water，or specific solids)and set the experimental temperature．By observing amplitude changes in the waveform graph and the dynamic evolution of preliminary patterns，the speed of sound is measured using two methods:the resonance interference method and the phase comparison method．Multiple simulation results show that the relative error between the measured and theoretical values of the speed of sound is consistently below 0．10%，demonstrating the high accuracy and stability of the simulation．This platform visualizes experimental details more concretely，enhancing the understanding of experimental principles，and is worthy of promotion as a teaching aid．
