 Floor speakers, wall speakers or suspension speakers, its vibration can be passed to the floor or wall, inspired by the vibration of the floor or wall, passed upstairs, radiated noise. Design according to the various types of speakers, including subwoofer and its total weight of the stent, a reasonable choice of "active damping" (elastic) within the rubber and spring shock absorber. 

 In short, the subwoofer structure-borne noise transmission, the control point is to cut off the "Sound Bridge", one of the subwoofer to take isolation measures to reduce the subwoofer sound through mechanical vibrations through the ground or ceiling "sound bridge" passing noise using rubber vibration reduction measures; second is to strengthen the ground, concrete pillars, ceilings, less power walls, sound insulation of the pipe, reduce the subwoofer have a strong airflow to stimulate the "sound bridge" and pass the noise, noise carpet and auxiliary rock wool and a certain layer of air, to avoid simply using rockwool and a certain air layer, so the sound will be almost no loss through its excited "sound bridge" to pass the structure-borne noise. 


 SoundBridge: 

 The double-wall air layer between the solid rigid connection should be avoided. Almost hear the bridge exists, will undermine the role of the elastic layer of the air layer, so that the decline of sound insulation. 

 The hollow part of hollow slab wall or hollow block wall, can reduce the wall weight, but unfavorable to the sound insulation. Slab, hollow block like building components and masonry up an empty bucket wall cavity can not be mistaken for that from the sound insulation effect of the air layer. Because the cavity is surrounded by the sound of one hundred percent of the rigid connection bridge, totally can not afford the elasticity of the air layer.
