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

    Frequently Asked Questions

    • Industrial acoustic doors are specialised doors designed to minimise the transmission of noise in industrial settings. They typically feature heavy-duty construction and specialised soundproofing materials to achieve this goal, distinguishing them from regular doors.

    • Industrial acoustic doors employ various soundproofing techniques, such as multiple layers of dense materials, acoustic seals, and specialised construction methods to reduce noise transmission. These features help create a barrier preventing noise from passing through the door effectively.

    • Factors such as the level of noise reduction required, the size and dimensions of the doorway, environmental conditions, and any specific regulatory requirements must be taken into account. Additionally, considerations such as durability, maintenance requirements, and compatibility with existing infrastructure should also be considered.

    • Yes, industrial acoustic doors can often be customised to fit specific industrial environments. This customisation may include adjustments to size, materials, finishes, and additional features to meet the unique needs of the application.

    • The noise reduction ratings of industrial acoustic doors can vary depending on construction materials, thickness and design. However, they typically have high Sound Transmission Class (STC) ratings ranging from 40 to 60 or higher, indicating their effectiveness in reducing noise transmission.
