(The sound quality of the conference system hall is a generalized effect of architectural acoustics and electroacoustics. The acoustic condition is the condition, and the electroacoustic design is the foundation. As long as the construction sound is satisfied, the electroacoustic talent can be self-defeating and powerful; otherwise, even if the room is resplendent, the electroacoustic equipment is very particular, and the construction sound conditions are not satisfied, the buzzing sound is constant, the whistling One after another, the sound effect is not good.)
