PackSound Acoustic Project Case Study: PWD ITO Delhi with Ceiling Baffles & Composite Wall Panels

Understanding the Acoustic Challenge in PWD Buildings

Large administrative buildings like PWD offices are typically constructed with concrete, glass, tiles, and gypsum—materials that reflect sound rather than absorb it. Over time, this creates excessive reverberation, unclear speech transmission, and constant background noise. In such spaces, even normal conversations become distracting, and meetings suffer from poor intelligibility. The PWD facility at ITO Delhi had similar issues where sound waves were bouncing across ceilings and walls, creating a harsh acoustic experience for staff and visitors.

PackSound began with a thorough acoustic analysis to understand reverberation time, noise reflection points, and sound travel patterns. The study revealed that both ceiling and wall surfaces were major contributors to echo and sound build-up. A dual-surface acoustic treatment strategy was recommended using Baffles for ceiling to control vertical reflections and Composite panels for walls to manage lateral reflections.

Acoustic issues identified

• High reverberation time

• Speech disturbance in work areas

• Noise accumulation from foot traffic

• Hard reflective surfaces on walls and ceiling

• Lack of sound absorption materials

Why PackSound Recommended Baffles for Ceiling

Ceilings are often the largest uninterrupted surface in any interior, making them a primary source of sound reflection. Installing Baffles for ceiling was a strategic decision by PackSound to break the path of reflected sound waves vertically. These suspended acoustic elements are highly effective in absorbing sound from multiple directions while maintaining air circulation and lighting layouts.

The Baffles for ceiling used in this project were designed with high NRC (Noise Reduction Coefficient) material to significantly reduce echo and reverberation. Their suspended linear formation not only improved acoustic absorption but also added a modern architectural rhythm to the space. This solution allowed sound energy to be trapped and absorbed before it could reflect back into the room.

Benefits of Baffles for ceiling

• Excellent control of vertical sound reflections

• High sound absorption performance

• Modern, clean visual appeal

• Suitable for large government spaces

• Easy integration with existing ceiling services

Role of Composite Panels for Walls in Acoustic Control

While ceilings manage vertical sound waves, walls are responsible for lateral sound reflections. To address this, PackSound installed Composite panels for walls across critical reflection areas. These panels are engineered with layered acoustic materials that absorb mid and high frequency sounds, which are most common in speech and office noise.

The Composite panels for walls provided dual benefits: acoustic performance and surface enhancement. They helped in minimizing flutter echo between parallel walls and significantly improved speech clarity across rooms and corridors. Their durable finish also made them ideal for a high-traffic government environment where longevity is crucial.

Advantages of Composite panels for walls

• Controls lateral sound reflections

• Reduces flutter echo and harshness

• Improves speech intelligibility

• Durable and easy to maintain

• Enhances interior appearance

Acoustic Design and Installation Strategy by PackSound

A successful acoustic treatment depends not only on materials but also on placement strategy. PackSound followed a scientific installation layout based on acoustic mapping. Baffles for ceiling were placed in calculated intervals to maximize absorption coverage, while Composite panels for walls were installed at first reflection points and high-impact zones.

The installation was executed with minimal disruption to daily operations at PWD. Precision alignment, secure suspension systems, and clean finishing ensured both safety and aesthetics. The final outcome was a balanced acoustic field where sound behaves predictably and comfortably.

Installation approach

• Acoustic mapping before execution

• Strategic placement of panels and baffles

• Safe suspension and mounting systems

• Minimal operational disturbance

• Professional finishing standards

Results Achieved After Acoustic Treatment

Post-installation measurements showed a remarkable reduction in reverberation time and noticeable improvement in speech clarity. Staff reported less noise fatigue, better communication, and a more pleasant working environment. Visitors experienced clearer announcements and conversations without the typical echo found in large buildings.

The combination of Baffles for ceiling and Composite panels for walls proved to be highly effective in transforming the sound behavior of the space. This project stands as a practical example of how the right acoustic treatment can improve functionality in government infrastructure.

Outcomes

• Reduced reverberation and echo

• Improved speech clarity

• Comfortable sound environment

• Professional interior aesthetics

• Long-term acoustic performance

Why This PackSound Project is a Benchmark for Government Buildings

Government buildings require solutions that are durable, efficient, and low maintenance. This project at PWD ITO Delhi demonstrates how PackSound products meet all these requirements while delivering high acoustic performance. The use of Baffles for ceiling and Composite panels for walls created a scalable model that can be replicated across similar facilities.

This case study serves as a reference for future acoustic treatment projects in administrative, institutional, and public buildings where sound comfort is essential but often overlooked.

Project significance

• Ideal model for public infrastructure

• Long-lasting acoustic solutions

• Low maintenance requirements

• Replicable design strategy

• Trusted execution by PackSound
