The Whisper V3 (WSP3-27U-610) is a 27U - 1746mm (with castors) high active sound-proof server rack, 636mm wide x 1092mm deep, with an internal usable depth of 850mm.


Whisper V3 Soundproof racks is the latest generation in the Whisper range. Designed and manufactured to reduce the unacceptable levels of noise from servers, our in house tests have shown by up to 46.6dBA. Incorporates ultra quiet fans, barrier soundproof foam, sealed doors and a washable inlet dust filter. As a result Whisper rack is a real alternative to building server rooms / closets; since IT equipment like servers and network switches can now be located in general office space.
The original Whisper rack proved both successful and popular; building on the experience we have made a number of changes. The new V3 is more acoustically efficient than the previous version, it encourages front to back cooling, something server manufacturers strongly recommend. The airflow has been increased by 60% providing much improved cooling while the acoustic reduction has also improved by around 10%.

Most alternative acoustic racks are much larger then expected, taking up valuable room space. Some racks cannot be sited with the back close to a wall since they have back-mounted fans. This also means that the rack cannot be placed in a corner, often where most people want it. The Whisper V3, does not have any of these limitations. The Whisper is barely no deeper or wider than a standard rack and, due to the ultra-quiet vertical airflow, can be placed in any office corner out of the way.

The decibel (dB) is a logarithmic unit, for example, an increase of 3 dB is a doubling of the strength of the sound, an increase of 10dB means that the sound is 10 times as loud; i.e., 70 dB is 10 times as loud as 60 dB. 
Most people are not familiar with Acoustics, therefore we have tried to explain below what you can expect in simple terms. For a detailed explanation on Acoustics and Decibels please see http://en.wikipedia.org/wiki/Decibel_(Acoustics)

 

Examples of sound levels in common environments:

95dBA = Electric Drill

74dBA = Fully populated blade server running at 80% load

60dBA = Average Server

60dBA = Normal conversation

55dBA = Background noise in an average office

35dBA = A quiet library


Whisper V3 - Noise reduction results:
The chart below shows results from tests that we carried out on the Whisper V3. You will notice that significant reductions are achieved. A 46.6dBA reduction was achieved when tested with a source noise of 90dBA, however most applications do not have such a loud source. 

Looking at a fully populated blade server which was tested the noise level was reduced from 74dBA to 35.7dBA. As that is less than most background noise is an average office, the server noise will go unnoticed and will no longer be intrusive. No other acoustic soundproof rack at this price can keep noise level below "Å“background noise in an average office" for the spectrum of sound source that we used for testing.

Test Method 
The tests were based on a Blade Server and was tested using a Digital Impulse Sound Level Meter, the meter was placed at the source and the figure of 90dBA was recorded. We then took the server and installed it into a Whisper V3 server rack. The Whisper rack was switched on (running 12 fans), a reading was taken one meter from the rack (based on research that most people do have at least 1 meter between the rack and personnel). The reading was recorded as 46.8dBA, therefore a noise reduction of 43.2dBA was achieved, the below chart shows other tests that we also performed.
