Industrial acoustic enclosure is a sandwich-panel shell that fully or partly encloses a noisy industrial machine: rigid steel outer face, perforated absorber inner face. Built with service doors, observation windows, ventilation silencers and vibration mounts. Delivers 15-35 dB ambient-noise reduction.
What is an acoustic enclosure?
An industrial acoustic enclosure is the shell built around a machine (generator, compressor, fan, pump, press, CNC, etc.). The outer face is hard stainless or galvanised steel; the interior carries a high-absorption layer and, where required, a mass barrier. Removable panels for service, an acoustic observation window, silenced cooling ventilation and a base vibration system are part of the standard design.
Sandwich-panel build
- Outer face: 1-2 mm sheet (galvanised, stainless, painted)
- Barrier layer: EPDM/PVC acoustic membrane (optional)
- Absorber: 50-100 mm glass wool / rock wool
- Inner face: perforated sheet — sound passes through
- Total thickness: 50 / 75 / 100 / 150 mm
Technical components
- Sandwich acoustic panels (Rw 25-40 dB)
- Service doors (acoustic gasket + magnetic seal)
- Acoustic observation window (laminated double glazing)
- Inlet/outlet silencer (mandatory)
- Vibration mount / spring isolator at the base
- Internal lighting and service socket
Performance
- Insertion loss (IL): 15-35 dB
- Shell Rw: 30-45 dB (panel class)
- Operating temperature: -20 °C / +120 °C
- Fire class: A1 (rock/glass wool), A2 (sandwich)
- IP rating: IP54 / IP65 (outdoor enclosure)
Where it is used
- Generator (genset) enclosure
- Air compressor and vacuum machinery
- Cooling-tower fan unit
- Industrial pumps and blowers
- CNC, presses and printing machinery
- Plastic injection and recycling lines
- Test and calibration cells
Design criteria
- Target IL: existing LpA − target LpA
- Cooling load: sizing of the silencer duct
- Service access: maintenance frequency vs. removable panels
- Vibration isolation: spring/rubber to the base
- Certification: CE, EN ISO 11546 (test standard)
Engineering process
1) Site measurement (LpA, frequency band, dB(A)). 2) Set target IL. 3) Add cooling load, service access and visual needs to the design. 4) Select panel class, silencer and vibration system. 5) Manufacture, install and verify.
