1) hybrid absorption
半主动吸声
1.
In this paper,a new hybrid absorption method is brought forward and a new hybrid absorption system is designed which is composted of a layer absorption material and movable rigid panel.
提出了一种新的半主动吸声方法,并设计了一种新的半主动吸声系统。
3) active sound absorption
主动吸声
1.
It is controlled with incident sound wave, yet active sound absorption is controlled with reflected sound wave and the absorption coefficient is maximal for the reflected coefficient is reached to zero.
而有别于主动消声的主动吸声方法是从噪声传播途径上和受声体进行控制,它的控制目标是使入射声波的反射系数很小或接近于零,形成“黑洞”现象,使得吸声系数达到最大,从而达到吸声降噪的目的。
5) semi-active vibration absorption technology
半主动吸振技术
1.
Magnetorheological elastomers and corresponding semi-active vibration absorption technology;
磁流变弹性体及其半主动吸振技术
6) Semi-active Vibration Absorbing System
半主动吸振系统
