Minima Of Radiated Acoustic Power Are Different From Structural Vibration

Structural vibration mechanism and control have been studied deeply over the last several decades. As the dynamic characteristics usually can be expressed in the form of natural frequencies (poles), antiresonances (zeros) or minimum response frequencies, it is an effective way to change the peaks and valleys of vibrating response by assigning desirable poles to avoid resonances or assigning zeros to certain locations. Although the mechanism of generation of sound is by structural surface vibration, they are different in some ways....
