| Abstract: | 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. |
