Soundproofing & Acoustics
Sound insulation (measured according to the latest ISO 23351-1 standard):
-
Plus: 32±3 dB (ISO Class A)
- Maximum discretion for concentrated work. Blocks sound in the speech range with peak values of over 38 dB.
(Important: The switchable “Smart Glass” option automatically includes the best possible plus sound insulation).
💡 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.
