The UCoustic family of enclosures have been designed to be more than just a state of the art sound proof boxes; they are also excellent data communication cabinets.
The combination of record breaking noise attenuation and thermal dissipation performance ensures the UCousticT family is a world class leader in its field.
For the uninitiated 28.5dBA is a massive noise reduction to achieve from a 19" Enclosure and to achieve this USystems have invested heavily in research and development, utilising state of the art technology and included the latest most effective acoustic materials available.
This amazing noise reduction has been achieved without compromise to cooling the active equipment housed within. In fact the UCousticT 9210 has been tested and achieves a staggering thermal capability of 7.2kw of heat dissipation.
So what does 28.5dBA noise reduction mean and what benefits do I get?
As with all sound proof enclosures, the performance of the UCousticT family relies upon the ingenuity of the enclosure design and the acoustic material used in order to remove as much noise from the enclosed sound source (e.g. servers) as is possible. Noise is measured in decibels (dBA) so when we claim 28.5dBA noise attenuation, we are basically saying this is the amount of noise we are removing from the sound source. So if the starting point of the sound source is 69dBA (equivalent to a vacuum cleaner at 3m) then by removing 28.5dBA will be the equivalent of reducing the sound source down to say 'quiet speech' (see chart below) putting this into context, the cabinet placed in an office environment which can sit anywhere between 48dBA (average office without speech) and 78dBA (busy office with speech), then basically this is a long winded way of saying you will not be able to hear the original sound source from within the UCousticT Cab - unless you had your ear pressed up again the cabinet!
The chart below details the effect of housing noisy active equipment within an UCoustic Cab.
Let's be clear, an acoustic cabinet is designed to attenuate (reduce) the noise source and assist in the cooling of the equipment. Unfortunately removing heat means providing air paths and this in turn means that if the sound source is very loud then you WILL hear some noise emanating from the cabinet. The skill is to remove as much of the noise without detriment to the equipment.
To further simplify the true meaning of our achievements we have set up a basic example you can listen to online. In brief what we are demonstrating is the effect of removing varying levels of noise from an original sound source. For this example we have a recording of an Intel Blade Chassis which was running around 78dBa. To simulate the effect of housing this server into a noise reducing enclosure we reduced the sound level down at varying levels and rerecorded the net results. It should be noted that this noise reduction is just that, a sound reduction and does not deal with the softening of the frequency levels that a UCoustic Cab will also provide, so the resulting noise should you be able to hear any is even easier on the ear. We started by removing only 2 decibels, which is the effect you will get by putting equipment into any metal 19"enclosure, then 10dBa, 20dBA and finally clicking on the last icon demonstrates the outstanding performance attained by the UCoustic Cab at 28.5dBa.
To listen to a comparison of our test results please follow the guidelines below: Clink on the first icon, the noise you will hear is an Intel blade server. What we need to try and recreate is the true 78dBA noise level of the original recording. Unless you have a sound meter this is impossible, however 78decibels is uncomfortable to human ears, its not deafening but you would not want to be sitting next to it in the office. We need you to adjust your PC speaker volume so that the white noise server noise that you hear is uncomfortable to the ear but not painful, see above chart for noise comparisons. Unfortunately most PC speakers are not powerful enough or have the frequency range to replicate the sound power and frequency combination of a blade server, so the likelihood is that the speakers will need to be fully turned up. Whilst we cannot guarantee the noise level you will be listening to, through trials we have carried out we are confident you will be able to replicate the experiment sufficient to show the varying levels of noise attenuation gained by putting active equipment within an UCoustic Cab. Once set do not readjust your speakers and simply click on each sound icon, finally clicking on the UCoustic Cab level and hear the difference!
