NoiseTrap® Acoustic Panels
We design and manufacture a complete line of modular engineered systems incorporating NoiseTrap® acoustic panels.
With superior low-frequency performance, specifically targeted for power transformers, a NoiseTrap®panel achieves up to 34 dB attenuation for 100 Hz tonal applications, with an absorption coefficient of 1.00, whilst maintaining high transmission loss at higher frequencies, Rw (C:Ctr) = 44 (-1;-2 dB).
Our innovative solutions stand up to the closest scrutiny and exceed the toughest of contractual expectations, enabling Sonobex to guarantee the acoustic performance of each design.
No Acoustic Infill
Conventional solutions typically contain absorptive materials inside to achieve decent levels of noise reduction, but limited low-frequency performance. Infill materials typically degrade due to contamination and ingress of water, reducing its acoustic performance over its lifetime.
A NoiseTrap® panel is a completely galvanized steel construction that consists of coupled resonator elements that attenuate airborne noise; as such a NoiseTrap® panel has no acoustic infill or lining materials to provide acoustic performance.
An infill free NoiseTrap® panel, therefore, has a very high through-life performance compared to traditional solutions with little or no degradation of acoustic performance over time.
NoiseTrap® panels can be used where there is to be no risk of fibre migration or contamination such as food production plants and hospital environments. The complete absence of infill also facilitates ease of cleaning and drainage, making NoiseTrap® panels well-suited for chemical plants, refineries, and facilities handling hazardous materials.
Due to the uniqueness of the technology, panels can be designed with passive ventilation in mind in order to dissipate heat, renew ambient air and to evacuate gas leaks.
Sonobex has engineered a range of attenuating NoiseTrap® panels that allow air to pass through the apertures whilst reducing the noise transmission to the environment.
NoiseTrap® panels can be incorporated into a fully ventilated acoustic enclosure, in some cases removing the need for forced ventilation.
Freestanding barriers benefit from reduced wind loads; lowering foundation and installation costs.
Sonobex undertake computational fluid dynamics and conjugate heat transfer to optimise acoustic performance with airflow requirements.Learn more
NoiseTrap® panels can be used to construct simple acoustic shields to large acoustically isolated industrial buildings and is structurally designed for internal and external loading; the integrated steel frame systems carries the static and dynamic loads.
The integrated structural steel framing system enables a modular panel-to-panel construction to be utilised for smaller enclosure systems (up to a height of 6.5m).
Larger enclosures can be as easily realised by incorporating NoiseTrap® panels into a steel framework offering increased rigidity for specific applications.
The NoiseTrap® LF Series of acoustic panels is suitable for most industrial applications including:
Power and distribution transformers
Gas / steam turbines
Pumps and compressors
Mechanical plant machinery
Diesel and gas generators
