Executive standard: GB/T20291.1-2014 IEC 60312-1:2010

The sound box is designed as a double-layer vibration isolation structure: the soundproof box shell (the same inner shell) is made of 2.0mm thick high-quality cold-rolled electrolytic 304 stainless steel steel plate and multi-layer Spanish imported damping and sound-absorbing materials. The exterior can be decorated according to user requirements. The double-layer shells are suspended and filled with soft vibration isolation materials. There are silencing cavities on six sides of the inner layer of the box, and high-grade elastic sound-absorbing splinter modules are installed. Layers of sealed soundproof doors, the box is equipped with a test bracket, and the entire soundproof box is placed on a nonlinear low-frequency damping shock absorber. It not only isolates the airborne sound, but also isolates most of the vibrational sound.

Technical Parameters:

When the external environment noise is not more than 65dB, the background noise inside the box is ≤25dB(A)
