- To comply with occupational health and safety regulations and insurance guidelines
- A 5dB(A) reduction can cut the risk of hearing loss in half.
- Increased productivity – research shows prolonged exposure to noise creates stress, lowers moral and can lead to increased accidents and /or errors in the workplace.
- Noise is measured in decibels so when we claim 28.5dB(A) 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 a bit nebulous. A soundproof (or sound reducing) enclosure is going to remove a specified amount of noise (decibels) from the surrounding area, according to how it was designed and manufactured. Your sound reduction result is dependent on the amount of noise in the location you are trying to subdue.
The UCoustic 9210 range of 19-inch soundproof rack mount cabinets are the only commercially available network/IT cabinet in the world proven to deliver a sound reduction of 28.5dB(A) and a heat dissipation of 7.2KW.
To put this into non-technical terms, human conversation measured at a distance of three to five feet away ranges between 60 and 70dB(A). If the speaker increases their volume by just 10dB(A) the human ear will perceive this as a doubling in the noise level: an increase of 20dB(A) will be perceived as a quadrupling of the noise.
Our UCoustic 9210 network/IT cabinet range delivers a noise levels reduction equal to about five times less than that produced by your current rack mount equipment.
In an IT/Network context, the typical noise from two low form factory servers with an average CPU loads is 62dB(A): Four servers is 65dB(A): Eight servers, 68dB(A)*. With a UCoustic™ soundproof cabinet placed in an office environment – typically between 48dB(A) (average office without speech) and 78dB(A) (busy office with speech) – you will not be able to hear the sound from within the UCoustic™ Cabinet unless you had your ear pressed up against it.

The importance of temperature control
- Excessive heat prevents cabinets from being populated to their full potential
- Excessive heat can result in server shut-downs
- Excessive heat 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 UCoustic 9210 range dissipates the heat produced by servers, disk drives and controllers by up to 7.2KW.
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.
Our customers have found the UCoustic 9210 range allows up to twice as many servers and components to be mounted in a single cabinet without exceeding manufacturers operating temperature guidelines. Noise levels drop to where the noise produced by the cooling fans in desktop systems exceeds that produced by densely populated cabinets.
To achieve the maximum heat dissipation 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 7.2KW in an active cabinet and by up to 2.75KW in a passive cabinet. These figures have been independently verified by MIRA Labs to measure the heat dissipation.
