Sonic acoustic enclosure
Custom-engineered acoustic solutions for equipment noise control

-
Backed by the Science of Silence
Part of the Flexshield Group
Manufactured by Flexshield, AcousTech Sonic acoustic enclosures are built in Australia using durable materials and precision fabrication for consistent performance across site conditions.Trusted by engineers and built for performance
Engineers specify Sonic acoustic enclosures for their proven noise reduction, structural flexibility, and reliability in high-noise industrial and infrastructure settings.
Key Applications
- Data centres and BESS infrastructure
- Power distribution, generators and industrial motors
- HVAC plant, chillers and plant rooms
- Test cells and validation bays
- Material processing and handling systems
- Mining and resources facilities
- Packaging, filling and bottling lines
- Manufacturing noise zones
- Water treatment and pump stations
Performance
A Sonic acoustic enclosure is only as good as the components it’s built from. Every panel, louvre and door has been tested in NATA-accredited laboratories, so the performance we specify is the performance you can expect on site.
Typical system performance by frequency
- Low frequency (125 Hz): 15 to 25dB reduction
- Mid frequency (500 Hz): 25 to 35dB reduction
- High frequency (2000 Hz): 35 to 45dB reduction
Component ratings
- Sonic System acoustic modular panels: up to Rw 45dB (V100SP)
- Sonic Series acoustic louvres: up to Rw 33dB (SL4-60C)
- Sonic Access acoustic doors: up to Rw 52dB (high performance)
- Sonic acoustic curtain: up to Rw 30dB (to confirm)
Fire resistance level for all Sonic System modular panels: -/120/- to AS 1530.4-2014.
Ventilation and cooling are sized to keep the equipment inside operating safely, and access points are planned for serviceability, maintenance and safety.
Construction
Every Sonic acoustic enclosure is custom-built from modular components and tailored to your site. Depending on the equipment and the environment, we’ll specify a combination of:
- Sonic System acoustic modular panels (V50, V100, V100SP, V225 or VR roof panels)
- Sonic Series acoustic louvres for ventilation with noise control
- Sonic Access acoustic doors for personnel and equipment access
- Sonic acoustic curtain where flexibility or a partial enclosure is needed
Each enclosure is designed to include, as required:
- Ventilation and airflow provisions
- Vision panels and lighting
- Cable, duct and service penetrations
- Removable roof or wall sections for equipment access
- Lifting points and a certified support frame
Testing & Compliance
Every enclosure is engineered to meet site, equipment and legislative requirements.
- Acoustic testing: conducted in NATA-accredited laboratories
- Sound insulation: AS/NZS ISO 717.1-2004
- Noise emission: AS 1191-2002
- Fire rating: to the relevant NCC provisions and AS 1530.4-2014
- Structural integrity: engineering certification available
- Environmental compliance: based on application and jurisdiction
- Work health and safety: considered in all access and service zones
How To Specify
A successful enclosure project starts with a full understanding of your acoustic, structural and operational requirements. We work through three stages with you.
Stage 1 – initial assessment
- Equipment type and size
- Site layout and constraints
- Target noise reduction levels
- Access needs for personnel and equipment
- Ventilation and heat load
- Maintenance and inspection frequency
Stage 2 – system design
- Acoustic performance targets
- Panel type and thickness
- Airflow design and cooling strategy
- Door and access point placement
- Lighting and service integration
- Structural and support requirements
Stage 3 – final configuration
- Finishes, colours and branding
- Vision panels or inspection windows
- Cable, pipe or duct routing
- Lifting or transport requirements
- Monitoring systems or alarms
Our process
- Initial consultation
- Site inspection
- Acoustic measurement and modelling
- Custom enclosure design
- Engineering documentation and certification
- Manufacturing in our Australian facility
- Delivery and installation
- On-site performance verification
