The noise reduction testing system is designed by our company based on standards such as ISO3745-2003, IEC60312, GB6882, ISO7779, GB/T4214.1, GB/T4214.4, and GB/T3767 for the anechoic chamber. The acoustic indicators in the design include background noise, cutoff frequency, usable space, vibration reduction, etc.

  While ensuring that the test room meets acoustic specifications, the design also takes into account factors such as ease of use, instrument wiring, monitoring conditions, and indoor environment.
