Acoustic Fit-Out Case Study: Siren Headquarters

Requirements:

Siren required a comprehensive acoustic and AV solution to optimize the functionality of their Boardroom and Phone Booths. Key requirements included:

• Achieving specified Reverberation Time (Tmf) targets for improved acoustic performance.
• Seamless integration of wall-mounted sound-absorbing finishes that complement the aesthetic of the spaces.
• Installation of advanced video conferencing hardware in the Boardroom.
• Effective sealing of doors to minimize sound leakage.
• Post-installation acoustic testing to ensure the design meets performance benchmarks.

Analysis of Requirements:

1. Acoustic Challenges:
   
   • Spaces such as the Boardroom and Phone Booths required precise acoustic treatment to reduce reverberation and improve clarity.
   • Achieving the desired acoustic performance while maintaining the visual appeal of the spaces was critical.
2. Video Conferencing Needs:
   
   • The Boardroom required a state-of-the-art video conferencing system with advanced features such as AI-assisted audio optimization, high-resolution video, and multi-platform compatibility.
3. Door Soundproofing:
   
   • Effective door seals were necessary to prevent sound leakage, ensuring privacy and enhanced acoustic performance.
4. Compliance with Standards:
   
   • Post-installation acoustic testing had to comply with ISO 3382-2 standards, ensuring the results met international benchmarks.

Solution:

1. Design Works:

• Developed 3D Room Acoustic Models for the Boardroom and Phone Booths using ODEON Room Acoustic Modeling software. This enabled precise specification and placement of wall-mounted sound-absorbing finishes.
• Predicted and iteratively refined the Reverberation Time (Tmf) to ensure the spaces met the acoustic targets.
• Prepared material layout drawings for client approval, ensuring the finishes aligned with Siren’s aesthetic requirements.

2. Acoustic Installation:

• Door Seals:
  
  • Installed head, jamb, and drop seals for doors in the Boardroom and Phone Booths. The seals were colour-matched to the door frames for seamless integration.
• Room Acoustic Finishes:
  
  • Boardroom:
    
    • Side Wall and Screen Wall: Installed Artnovion Myriad AE panels (colours chosen in consultation with the client).
    • Back Wall: Installed Artnovion Mirage panels with a custom Siren logo graphic. Fixtures were relocated or integrated as needed.
  • Phone Booths 1, 2, and 3: Installed Artnovion Mirage panels on the back wall, ceiling, and side walls.

3. Video Conference Hardware Installation and Integration:

• Installed the DTEN D7X 55” system in the Boardroom, integrated with the existing network over Cat6 connectivity.
• Key Features:
  
  • 4K camera with a 129° viewing angle and auto-framing.
  • AI-assisted audio optimization and echo cancellation.
  • 15-microphone array for clear and focused speech.
  • Multi-platform compatibility with Zoom, Microsoft Teams, and more.
  • BYOD functionality for easy screen sharing via USB Type-C.

4. Acoustic Commissioning Testing:

• Conducted post-installation testing to verify that the achieved Reverberation Time (Tmf) met the target requirements.
• Issued a detailed report in compliance with ISO 3382-2 standards, documenting the acoustic performance results.
