Backed by the Science of Silence
Part of the Flexshield Group
Manufactured by Flexshield, AcousTech Sonic Access acoustic doors are built in Australia with proven designs, tested materials, and reliable lead times.Trusted by engineers and built for performance
Engineers specify Sonic Access acoustic doors because they integrate seamlessly into larger systems and deliver verified acoustic results on site.
Key Applications
Sonic Access acoustic doors deliver airborne sound insulation of Rw 46dB (single leaf) and Rw 45dB (double leaf), with a Rw 52dB option available for higher performance requirements. They’re specified on infrastructure and building services projects where noise from plant and equipment has to be contained.
Typical applications
-
Data centres and BESS infrastructure
- Plant rooms and mechanical services areas,
- Pump stations and water treatment infrastructure
- Power generation facilities and substations
- Manufacturing and processing plants
- Acoustic enclosures and equipment housings
- Control rooms in industrial environments
Performance
Sonic Access – single leaf door
- Acoustic rating: Rw 46 (-1, -3) dB, confirmed by NATA-accredited laboratory testing
- Application: Personnel access in high-noise industrial environments. Typical locations: Plant rooms, mechanical services areas, control rooms, processing facilities, equipment enclosures
- Function: Maintains acoustic separation while allowing routine operational access
Sonic Access – double-leaf door
- Acoustic rating: Rw 45 (-1, -3) dB, confirmed by NATA-accredited laboratory testing
- Application: Wide access openings where sound isolation has to be maintained.
- Typical locations: Pump stations, substations, water infrastructure, energy facilities, defence projects, manufacturing plants, acoustic enclosures.
- Function: Provides large-span access without reducing acoustic performance
