The Urban-Line is the highest-quality product line from SoSilent and stands for maximum acoustic performance, precise craftsmanship, durable materials, and a clear, modern design.

Soundproofing (Measured according to the latest ISO 23351-1 standard):

💡 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 volume of about 45 dB. When our speaker attenuates a conversation to 30 dB, the room swallows up the residual noise – practically inaudible to the team outside.
