MARA Knurr productWhat Noise Reduction Can I Expect from AcoustiRACK® Active Quiet Rackmount Cabinets?
Comparing Manufacturers' claims for noise reduction can be very misleading because of widely differing test methods.
Also, enclosures with similar decibel noise-reduction ratings may sound very different to the human ear, as some acoustic racks dampen the more noticeable noise frequencies better than others.
To help you make an informed choice we have independently tested all the Quiet Rack ranges side by side enabling us to recommend the right Quiet Rack to meet your needs. You are also welcome to compare the racks for yourself in our unique Quiet Rack Demo Room.

AcoustiRACK® ACTIVE Range of Soundproof 19" Rackmount Cabinets incorporating ANC Technology
Models: 15U & 33U (Depth Options: 1000 / 1100 / 1200mm)
The AcoustiRACK® ACTIVE quiet server cabinet uniquely combines unrivalled noise reduction, high thermal dissipation and dust-filtered protection for 19 inch rackmount equipment.
This sound-proof rackmount cabinet range represents a breakthrough in being the first hardware enclosure range to incorporate proprietary Active Noise Control (ANC) technology resulting in a truly near-silent rackmount cabinet.
Silentium's proprietary noise-cancelling technology is highly effective in reducing low-frequency noise. When combined with traditional soundproofing techniques this rackmount cabinet achieves unprecedented spatial broadband noise reduction over the entire frequency bandwidth of the audible spectrum.
