摘　　要：深入研究了调频电台使用过程中经常产生的单音和啸叫两种声音特效,利用傅立叶级数进行数学建模,通过曲线拟合方法进行对比选择最佳模拟单音策略,并且通过实验测定模拟产生啸叫的基波振幅和基频取值范围,借助VB和C++语言实现该声音特效模拟仿真。通过实验测定和工程实践,证明该模型能够有效地解决电台声音特效的模拟仿真问题,提供了一种行之有效的解决思路。This paper studies two kind of special effect sound in-depth,both single-tone and squeak which are very common in the use of FM radio,the mathematical modeling is acquired by Fourier series,gives the best simulation strategies for single-tone by the contrast of curve fitting method,gets fundamental wave amplitude and frequency,realizes the special effect sound by VB and VC＋＋.The model is an useful resolvent for simulating special effect sound of FM radio testified by experimental determinaton and application,gives an effective way.
