摘要
介绍了声压级的三种计量表示式,声压级平均值和总声压级值的计算方法,引用现有的标准和规范对扩声系统的最大声压级的物理意义进行讨论,指出现行标准中对最大声压级的定义及其测量方法存在意义模糊之处,并引入相关的解决方法.
Three measurement expressions of the sound pressure level, the mean of sound pressure level and total sound pressure level are introduced. According to the existing national standards and criterion, the physical significance of the maximum sound pressure level in the hall is discussed, and it is pointed out that there are some ambiguity and the corresponding solutions.
