Project Overview

NAMO Medical Education & Research Institute, Silvassa, developed under the Ministry of Health & Family Welfare, Government of India, is located on a 20-acre campus in Silvassa, the capital of Dadra & Nagar Haveli.

It offers an annual intake of 177 medical students and includes academic buildings, hostels, and residential quarters.

The college is affiliated with Shree Vinoba Bhave Civil Hospital, a 650-bed facility (soon to be 1250 beds), initially established in 1952.

NAMO Medical Education & Research Institute, 4.3Km from the Hospital, features modern OTs, an auditorium, and seminar halls with professional AV systems. Inaugurated by PM Narendra Modi on 7th March 2025.


What did the client want to achieve?

The client requires a rugged and efficient audio conferencing solution integrated with a video system for their Auditorium, Conference Room, and Modular Operation Theatres. The main challenge is in the Modular OTs, where the walls and ceilings are made of EGP-steel, causing excessive audio reflections that lead to feedback loops. Additionally, the presence of Air Handling Units (AHUs) generates high ambient noise, affecting speech clarity and disrupting communication during conferencing.

To address these issues, the proposed solution should be capable of advanced echo cancellation, ambient noise suppression, and ceiling-mounted microphones optimised for reflective environments. The design should ensure reliable audio pickup and minimal interference, even in high-noise settings. The system to be engineered for seamless integration, high speech intelligibility, and long-term durability, aligning with the performance and operational efficiency across all designated areas.


Scope of work your company was involved in

We were engaged as an ELV System Integrator for a range of systems, including Professional AV System, Structure Cabling System, Enterprise Grade IT and AV Network, Security and Surveillance System, Fire Alarm & Public Address System, and Building Management System. The total project size was in multiple phases, valued at around 15.5 Cr for the Supply, Installation, Testing, and Commissioning.


What Key Challenges were faced?

During the implementation phase, several technical challenges were encountered in the Modular Operation Theatres (OTs). The use of EGP-steel modular walls and ceilings resulted in highly reflective surfaces, causing persistent audio feedback loops that disrupted communication. In addition, the high ambient noise generated by the Air Handling Units (AHUs) significantly reduced the signal-to-noise ratio, negatively affecting speech intelligibility for far-end participants during audio conferencing sessions. Furthermore, the installed Biamp DSPs, which utilised the “Launch” auto-calibration algorithm for ceiling microphones and speakers, were unable to perform accurately due to the elevated noise environment. The algorithm relies on low ambient noise levels to detect reference test tones, and the excessive background noise rendered the AI-driven auto-tuning process ineffective.


How were those challenges resolved?

To address the acoustic challenges, a comprehensive manual calibration was conducted. This involved precise adjustments to the gain structure, detailed equalisation (EQ) tuning, and optimisation of Acoustic Echo Cancellation (AEC) parameters to eliminate audio feedback and improve speech clarity effectively. Additionally, signal routing paths were refined, and microphone lobing angles were strategically configured to reduce the pickup of ambient noise sources such as the AHU. These measures collectively enhanced overall audio performance, ensuring clear and reliable communication within the acoustically complex environment.


How has your work helped the client

We have successfully commissioned Modular Operation Theatres, Auditorium, and Conference Room, all of which are now fully operational. A TELEVIC audio conferencing solution, integrated with a video system, has been deployed, enabling seamless two-way communication between Operation Theatres and various locations within the Namo Medical Education & Research Institute—such as the Seminar Hall, Auditorium, Board Room, and Classrooms—over a 4.3 km wireless radio link from the hospital. This setup supports live audio and video streaming from the operating theatres, allowing students to observe procedures in real time while also enabling recording for compliance and archival purposes. The entire solution is implemented over a geographically distributed wired and wireless network infrastructure, ensuring robust and scalable connectivity. The system allows for streaming to a variety of platforms and applications, including Zoom, Microsoft Teams, Webex, and social media channels like YouTube and Facebook, thus maximising accessibility, reach, and educational impact.


What are you most proud of about the project?

The NAMO Medical Education & Research Institute, located 4.3 km from the hospital, proudly houses state-of-the-art Modular Operation Theatres, a modern auditorium, and fully equipped seminar halls, all integrated with professional-grade audiovisual systems. This prestigious facility was inaugurated by the Hon’ble Prime Minister Shri Narendra Modi on 7th March 2025, marking a significant milestone in advancing medical education and healthcare infrastructure in the region.
