Noise-canceling
Protecting yourself from ambient noise is an important part of everyday life. We can offer sound-reducing front doors from 35 dB up to 44 dB,
good alternative to loft corridors or heavily trafficked areas. Our 44 dB door is also available with security class SS EN 1627-RC3.
Brief explanation of the different sound levels:
35dB: Conversation at normal level cannot be understood but can be heard to some extent at increased volume
40dB: Calls cannot be intercepted, but shouts and screams are faintly heard
45dB: Calls cannot be intercepted and shouts and screams cannot be heard.
