  • Aiming at the difficulty in actual measurement of sound propagation,the two-dimensional enclosed space model of sound propagation system based on Maxwell's wave equation was established,the wave equation was discretized using Nyquist theory.The simulation arithmetic of two-dimensional enclosed space sound propagation system was built and realized using Matlab.The results showed that it can intuitively show of sound in a enclosed space condition, record enclosed space acoustic field each point changing with time, and it is easy to realize for two-dimensional enclosed space sound propagation process observation and measurement.
