The acoustic feedback can directly affect the sound quality of the sound amplification system.When it gets serious,the stability of the system will be damaged.Therefore,when we use the public address system in the site,the necessary measures should be taken to restrain the feedback.This thesis is on the basis of the formation and then endanger of the acoustical feedback,and then analyzes the causes of the acoustical feedback.Finally,it focuses on discussing the inhibition of acoustic feedback in terms of the Amplitude condition and the Phase conditions.
