本文给出传声增益的计算方法,并用声反馈系数的测量来决定传输响应中最大峯级和平均级之间的差值.它可简化测量技术,并能用于扩声系统的声学设计. In this paper, the method of calculating the sound transmission gain is given and the difference between the maximum peak level and the average level in the transmission response is determined by the measurement of the acoustic feedback coefficient, which simplifies the measurement technique and can be used for acoustic design of the sound reinforcement system.
