Mission-Critical Facility
ISRO – Acoustic Treatment for Chandrayaan-2 Mission Control Room
MMT Acoustix partnered with the Indian Space Research Organisation (ISRO) to support the Chandrayaan-2 mission by improving the acoustics of its mission control room.
This high-tension environment demanded clear communication, reduced echo and fire-safe materials around sensitive equipment.
Using UL 94 fire-rated, high-density Pyramid Acoustic Foam, we helped transform the control room into an acoustically optimised workspace where scientists and engineers
can focus, collaborate and make critical decisions with clarity during mission operations.

Project
Chandrayaan-2 Mission Control Room
Scope
Acoustic treatment for echo and high-frequency noise control in a mission-critical workspace
Objective
Create an optimised acoustic environment that supports clear speech, focus and safety during high-stress mission operations.
Key Product Used
- Pyramid Acoustic Foam
- Density: 50 kg/m³
- Thickness: 75 mm
- Fire Rating: UL 94 certified
- Purpose: Echo control & high-frequency sound reduction
System Goal:
Deliver a controlled, low-echo acoustic environment in the control room that enhances speech intelligibility and concentration while fully complying with ISRO’s safety and technical performance standards.
Client Challenge
Clear Communication in a High-Stress Control Room
The Chandrayaan-2 mission control room is a precision-driven space where teams monitor and manage critical operations in real time. The acoustic challenges included:
- High Echo Levels: Reflective surfaces in the control room caused noticeable reverberation, affecting speech clarity.
- Sharp High-Frequency Sounds: Equipment noise and reflections created harsh, fatiguing high-frequency peaks.
- Safety-Critical Environment: Any solution had to be fire-safe and compatible with sensitive electronic systems.
Our Approach
Fire-Rated Acoustic Treatment for Mission Readiness
High-Density Absorption
- Supplied Pyramid Acoustic Foam with a density of 50 kg/m³ for robust, long-term performance.
- Selected 75 mm thickness to effectively tame reflections and high-frequency build-up.
- Optimised to reduce speech smearing and improve overall acoustic comfort for operators.
Strategic Panel Layout
- Panels placed on key reflective surfaces to break flutter echo and shorten reverberation time.
- Layout designed to avoid interference with displays, instrumentation and control equipment.
- Maintained clear sightlines and operational ergonomics within the control room.
Safety & Compliance
- Used UL 94 fire-rated material suitable for sensitive, mission-critical environments.
- Ensured the solution aligned with ISRO’s safety and performance requirements.
- Provided a low-maintenance, durable acoustic treatment suitable for continuous operation.
