摘要
室内扩声系统中普遍存在着声反馈问题，严重地影响了扩声质量和效果。本文针对声反馈产生的原因，从科学建声、扩声设备选择、扬声器系统布置、严格科学调试、正确操作使用等五个方面讨论预防声反馈的具体措施。
Acoustic feedback, a very common problem in the interior sound amplifying system,seriously affects the quality and effects of the sound amplificatin.This paper first explores the causes of the acoustic feedback, and then presents 5 effective ways to prevent it: scientific design of the interior acoustic; the proper choice of sound amplifying instrumnts; the arrangement of the cabinet speaker system; strictly scientific modulation adn correct operation.
