After the acoustic wave contacts the wall panel, in addition to the forced vibration in the vertical direction, the wall panel has forced bending vibration along the direction of the panel surface. At a certain frequency, the forced bending vibration will coincide with the inherent free bending vibration of the plate. At this time, the plate follows the incident acoustic bending very compliantly, causing the sound energy to be transmitted to the other side in a large amount to form a soundproof amount. The trough, this phenomenon is called the anastomosis effect, and this frequency is called the coincidence frequency fc.
