本文对厅堂扩声系统的最大粉红噪声声压级、传输频率特性、传声增益、声场不均匀度、失真等声学特性指标提出建议。它是以一些测量和使用效果的评价以及我国电声设备达到的使用特性为基础,还考虑了某些实验结果和国外达到的水平。当前对语言或演出用的扩声系统采用不同等级的声学特性指标是可取的。
This paper puts forward some suggestions on the acoustical properties such as the maximum pink noise level, transmission frequency characteristics, sound transmission gain, sound field inhomogeneity and distortion in the auditorium sound reinforcement system. It is based on the evaluation of some measurements and the effects of use and the characteristics of use achieved by our electro-acoustic equipment, as well as taking into account certain experimental results and levels achieved abroad. Currently it is advisable to use different levels of acoustic characteristics for sound reinforcement systems for speech or performance.
