SC200 sound proof box
When testing Bluetooth headsets, speakers, and speakers, it is used to simulate the anechoic chamber environment and isolate external Bluetooth radio frequency and noise signals.
It can assist R&D institutions that do not have anechoic chamber conditions to conduct accurate acoustic testing. The box body is a stainless steel one-piece molded edge-sealed structure with excellent RF signal shielding. Sound-absorbing cotton and spiked cotton are implanted inside to effectively absorb the sound.
It is a rare high-performance acoustic environment test box.
The size of sound proof box can be customized.
