Objective

To enhance acoustic comfort in a 15,000 sq. ft. terminal area at Delhi Airport by using high-performance acoustic panels. The project aimed to:

  1. Reduce Noise Pollution: Manage the high noise levels caused by foot traffic, announcements, and operational activities.
  2. Improve Passenger Experience: Create a serene and welcoming environment.
  3. Meet Aesthetic and Safety Standards: Blend with the airport's modern design while adhering to fire safety and durability requirements.

Background

Delhi Airport serves millions of passengers annually, with high noise levels in terminal areas impacting the traveler experience. The project focused on creating a quieter environment in waiting lounges, check-in areas, and food courts without compromising the design and operational efficiency of the space.

Challenges

  1. High Noise Levels:
    The terminal's open design caused sound to echo, amplifying noise from crowds, luggage movement, and public announcements.

  2. Design Compatibility:
    The panels needed to integrate seamlessly with the airport's architectural >

  3. Durability and Fire Safety:
    Materials had to withstand heavy usage, comply with fire safety regulations, and maintain long-term performance.

  4. Time Constraints:
    The installation had to be completed without disrupting airport operations.

Solution

High-performance acoustic panels were selected for their:

  • Sound Absorption: Panels with an NRC (Noise Reduction Coefficient) of 0.85 or higher to control reverberation and background noise.
  • Aesthetic Versatility: Customizable designs to match the terminal's modern interiors.
  • Durability and Compliance: Panels made of fire-retardant and impact-resistant materials suitable for high-traffic areas.

Implementation Plan:

  1. Assessment and Planning:
    Acoustic experts conducted a site analysis to identify areas with the highest noise levels and points of maximum sound reflection.

  2. Material Selection:

    • Wall Panels: Fabric-wrapped fiberglass panels for large walls in lounges and waiting areas.
    • Ceiling Panels: Suspended PET acoustic baffles in food courts and check-in areas to reduce ambient noise.
    • Design: Panels were customized with colors and patterns reflecting the airport’s branding and aesthetic.
  3. Installation:

    • Wall panels were mounted in passenger lounges and along walkways to absorb mid-to-high frequencies.
    • Ceiling baffles were suspended in a staggered pattern to manage sound diffusion and add a visually dynamic element.
  4. Operational Coordination:
    The installation was scheduled during off-peak hours to minimize disruption to airport operations and passenger flow.

Results

  1. Noise Reduction:

    • Overall noise levels in the terminal were reduced by 40%.
    • Improved clarity of public announcements and reduced background noise, enhancing communication efficiency.
  2. Enhanced Passenger Comfort:

    • A more serene and pleasant environment for travelers, especially in waiting and dining areas.
    • Positive feedback from passengers and staff about the improved ambiance.
  3. Aesthetic Integration:

    • Panels added a sophisticated touch to the interiors, maintaining a balance between functionality and design.
  4. Regulatory Compliance:

    • All materials met fire safety standards and were durable enough to handle high-traffic conditions.

Client Testimonial

“The acoustic panel installation has greatly improved the traveler experience at our terminal. The reduced noise levels and visually appealing design have been a valuable addition to Delhi Airport.”

Conclusion

The use of acoustic panels at Delhi Airport demonstrates the effectiveness of tailored acoustic solutions in managing noise and enhancing large, high-traffic spaces. This project serves as a benchmark for airports seeking to combine sound control, aesthetics, and safety.

Key Takeaway: Acoustic panels are essential for creating quieter and more comfortable environments in high-traffic facilities like airports, offering both functional and aesthetic benefits.
