Electromagnetic radiation where the frequencies coincide with the resonant frequencies of the organism may stimulate energy which suppresses development of micro organisms and thereby reduces illness.
与生物体共振频率一致的电磁辐射，激发一种抑制微生物生长的能量，从而降低疾病的发生机率。

Therefore, the randomness of viscoelastic damping layer obviously influences the resonant response and sound radiation of structure.
