摘要
本文提出了计算活塞型声场一种简单方法，将声源分布函数作为某一函数与矩形函数高斯和的乘积，而无需对每个声源分布函数的高斯分解系数进行数值求解，这种方法可大大减化声场计算，并计算了几种活塞型声场分布，结果表明这一方法相当有效。
in this paper, we present a simpler method to calculate the distribution of the pistonlike sound fields, which extends the approach proposed by Wen and Breazeale. The distribution function on the source is expressed as the product of one function and a Gaussian sum of the step function, and the calculation of the sound fields reduces the estimation of sums of some relatively simple functions such as the M-shape and Gaussian ones. Some of pistonlike fields are evaluated, and the results indicate that this approach is very successful.
