The central damping layer is made of high-elasticity aging resistant and flame retardant SBR high-density material, the front and rear surface boards are made of inorganic materials with different densities and different thicknesses to form the structural properties of sound insulation and vibration damping material and effectively insulate the vibration of medium-low frequency and sub-low frequency sound transmission.

Features

The soft sandwich cavity ensures that the airborne sound reduction index and the sound transmission effect of the shearing stress are effectively promoted, and the cavity dimension and the complex vibration damping structure can be reduced after the construction of sound insulation layer.

Application

Suitable for KTV, nightclubs, show bars, private theaters, HIFI listening rooms, piano rooms, recording studios and other active sound insulation structures.
