Soundproofing & Acoustics

💡 Good to know: How to read our acoustic values

  • Certified standards: Tested according to ISO 23351-1.
  • The masking effect: A normal office has a basic noise level of around 45 dB. If our box attenuates a conversation to 30 dB, the room absorbs the remaining noise - practically inaudible to the team outside.
