Wall shock absorber (also known as U-shaped spring hook, U-shaped shock absorber) is a vibration isolation and noise reduction component composed of excellent springs and synthetic rubber damping materials, designed as a bracket type buffering and vibration reduction hanger, using the principle of back pressure of rubber and springs.
Vibration sound is caused by the vibration transmitted to the air downstairs by the seismic source (the speaker vibrates directly or collides with the floor due to low frequency or other reasons, resulting in forced vibration), thereby transmitting sound energy to the rooms and surrounding passages upstairs and downstairs. In addition, vibration is also transmitted laterally to other floors of rooms along steel connections such as walls, floors, beams, columns, and foundations, causing solid sound transmission. Therefore, in order to reduce the sound pressure level of speakers (such as dance halls and disco's ultra-low frequency) and impact sound, in addition to controlling the vibration source, measures should also be taken to isolate the ultra-low frequency vibration and impact sound of the speakers in the vibration propagation path. Mainly through the surface layer, cushion layer, and ceiling, low-frequency vibration transmission and impact sound treatment are carried out.
The wall damper is composed of a U-shaped frame, damping rubber layer, and screw, which is easy and fast to install. And it can achieve good vibration isolation effect in engineering installation. Therefore, it has received the favor of a large number of acoustic installation companies.
