Brings forward adaptive noisereductionsystem based on short time average magnitude, expound its work principle and key technology, at last validate the compose is just through experimentation.
The SPRD will automatically open as the air pressure in the duct system increases, in order to prevent the reduction of air flow and excessive noise and velocity through the duct system.
当管道系统空气压力增加时,SPRD会自动开启,以防止管道系统中空气流动的减少和过度噪音和速度。
