声压波曲线的计算机模拟与分析

The computerized simulation and analysis of sound pressure wave

为研究声压波振幅规律,用M atlab软件模拟出声压波曲线,拟合出声压波峰值点的曲线与方程,并分析了吸收系数与反射系数对声压波曲线的影响。

To study the law of the amplitude of the sound pressure wave,by using Matlab,the sound pressure wave has been simulated,and also the curve and formulation of the peak point of the sound pressure wave have been found.Finally,the impacts of absorption coefficient and reflection coeficient to the sound pressure wave are analysed.
