Silentium specializes in developing innovative noise reduction products and solutions, combining proprietary ANC algorithms with acoustic insulation. They have collaborated with General Motors, Delphi, BEHR and Venmar, just to name a few, to find quiet solutions to fan generated noise ... and they are just getting started!

What's great about the AcoustiRACK ACTIVE?
  • May eliminate the need for a dedicated server room.
  • 100% portable – relocate where and when required.
  • Allows more densely populated cabinets.
  • 8kW heat dissipation – equivalent to the heat produced by seven, single-bar electric radiators.
  • Up to 30dB(A) equipment noise reduction – up to five times quieter than your existing cabinet.
  • Supports 2,204 lbs

Why do I need noise control?
  • A 5db reduction can cut the risk of hearing loss in half.
  • More productivity – research shows prolonged exposure to noise creates stress, may increase irritability and can lead to increased accidents and /or errors in the workplace.
  • Occupational health and safety regulations and insurance guidelines
  • Noise is measured in decibels (dBA) so when Silentium claims a 30dB(A) equipment noise reduction, this is the amount of noise being removed from the sound source (your server room or office).
  • Claims such as 90% noise reduction are not very accurate. A soundproof (or sound dampening) enclosure is going to remove a specified amount of decibels from the surrounding area, according to how it was designed and manufactured.
Why is heat control important?
The importance of controlling excessive heat within the rack:
  • Prevents cabinets from being populated to their full potential
  • Can result in server shut-downs
  • Can void manufacturer's warranties
While office/engineering room noise levels can make for an uncomfortable working environment, excessive heat can have a catastrophic effect on the reliability of any rack mounted installation, resulting in server shut-downs.

Excessive heat is also an expensive problem, preventing cabinets from being populated to their maximum capacity, requiring the purchase of additional storage solutions.

The Silentium AcoustiRACK ACTIVE™ MARA33U-1100 dissipates the heat produced by servers, disk drives and controllers by up to 8KW while providing up to30dB(A) of equipment noise attenuation. The rack itself produces some ambient fan noise, although it is generally absorbed as "white noise" in the room.

This is equivalent to the heat produced by seven, single-bar electric radiators, or about the same temperature required to heat a 100sq.m (1,000 sq.ft) room.

To achieve the maximum heat dissipation HotLok filler panels should be used to block all rack "u" not being used by the equipment on the front rails. This prevents warm air from recirculating in the cabinet. Warm air is evacuated through rear door fans at a rate of up to 8kW.
What is ANC Technology?
Silentium's AcoustiRACK ACTIVE is the only soundproof server rack to incorporate Active Noise Control (ANC) technology, and in this is different from the UCoustic Active and the AcoustiQuiet quiet racks.

Sound is a pressure wave, which consists of a compression phase and a rarefaction phase. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out - an effect which is called phase cancellation. Depending on the circumstances and the method used, the resulting soundwave may be so faint as to be inaudible to human ears. Check Wikipedia Active Noise Control for more info on this intriguing science.

The (2) Active Silenced Fan Trays, one located at the top and one at the bottom, literally "cancels" server noise. What's better than that?

The fan tray itself generates 47dB(A).
