The AcoustiRACK ACTIVE uniquely combines unrivalled noise reduction, high thermal dissipation and dust-filtered protection for the 19-inch IT equipment.
Silentium introduce a breakthrough in noise reduction performance with AcoustiRACK ACTIVE (ARA), a soundproof rackmount cabinet designed to reduce noise generated by servers and networking equipment.
This 22U quiet cabinet reduces equipment noise by 20dB(A) whilst allowing airflow for thermal dissipation of up to 5KW. This product is the most advanced solution for the growing IT noise problems faced by today's workforce.
Silentium's proprietary noise-cancelling technology is highly effective in reducing low-frequency noise. When combined with unique high-quality acoustic materials this product achieves unprecedented spatial noise reduction over the entire frequency bandwidth of the audible spectrum.
AcoustiRACK ACTIVE Benefits
- Quiet work environment - reduces noise pollution for people working in close proximity to hardware, reducing stress and improving focus and productivity. Numerous studies have shown that a quiet environment is conducive to improved cognitive function & decision making. Noise levels from 19" servers and networking/file storage equipment have been increasing steadily in recent years, with some units producing sound energy levels that become intolerable should you work close to them or in an adjacent room.
- High-capacity thermal solution - the advanced assisted venting design draws cool air into and forces warmed air out from the cabinet.
- A 'server room in a cabinet' - this flexible storage solution eliminates the high cost of allocating extra space or building a separate room for noisy IT equipment.
- Protects equipment from dust - unlike standard rackmount cabinets, the ARA features a filtered inlet for low dust environment, promoting equipment longevity and reducing maintenance costs.
- Flexibility of hardware choice - AcoustiRACK low noise enclosures allow companies and individuals a greater freedom of choice when selecting new 19inch equipment, and then to treat the noise generated. New equipment can be selected based on performance rather than low noise specifications.
- Health & Safety at Work - recent changes to directives & legislation show the general trend is one towards much lowered tolerance of workplace noise levels.
Active Noise Control (ANC)
Traditional noise reduction methods use foams and barriers. Even though they provide good results and are an important part of any noise reduction solution, they suffer from a major drawback: when implemented as sealing material, it blocks the airflow path, when lining ducts, it requires a relative long duct to achieve good results.
Silentium's innovative Active Noise Control solution provides you with the capability to allow airflow undisturbed while preventing noise from coming out. The concept of Active Noise Control (ANC) is based on producing an "anti-noise" signal which destructively interferes with the original sound and cancels out the original sound.
Silentium has developed a unique ANC concept incorporating proprietary innovative algorithms, which adaptively follow the changes in noise spectrum thus achieving extraordinary results of about 10dB(A) noise reduction. It allows undisturbed airflow path while preventing noise from being emitted. Unlike previously designed ANC systems, Silentium's solution is extending the low frequency range of signals, up to 1800Hz, and not only with single tones and eliminates the use of error microphones. The result is a small, low-cost highly effective solution to the low/medium-frequency noise, which can be applied to many different applications, thus producing a successful commercial solution.
