FAA-Compliant PA System Installation

Mission-Ready PA System Upgrade

Crunchy Tech partnered with the 157th Air Refueling Wing to bring a powerful new public-address system to Aircraft Hangar 254 at Pease Air National Guard Base. The goal was deceptively simple—loud, clear and reliable sound in every corner of the hangar. Our design and installation team successfully built a system that phenomenally handles crisp paging, safety calls and ceremony speeches. Importantly, the system satisfies FAA standards and keeps up with the no-nonsense demands of daily aircraft maintenance.

Extreme Acoustics and Safety Constraints

Project Challenges

Hangar 254 is a tough space for sound. In consequence, its massive open volume, reflective metal walls and exposed steel beams created serious acoustic challenges. Reverberation and slap-back made safety pages and operational briefings hard to follow. That’s a risk no one can afford in a fast-pacing maintenance environment.

The upgrade also had to respect aviation-specific requirements. Every component needed to clear aircraft wingspans; the system had to endure extreme and erratic temperature shifts; it had to run without disrupting flight-line activities. On top of that, all equipment and rigging had to pass stern federal regulations and base safety protocols. The margin for error? Zero.

Reliable Audio for Mission-Critical Operations

Understanding Client Needs

They needed a public-address system with superb speech intelligibility across the entire hangar. It must be able to handle routine maintenance briefings, emergency safety calls and formal military ceremonies with the same clarity and reliability.

Flexibility was just as important, if not more. Base leadership wanted control over all three audio zones. Either addressing them at once or targeting specific areas without affecting others. They also wanted wireless microphones that could hold multiple events simultaneously. That meant no signal dropouts whether it was a change-of-command ceremony or a guided visitor tour.

Working side by side with the client to strike the right balance. The system had to deliver top-tier technical performance while staying simple to operate. It also had to meet every regulatory requirement there is. With Crunchy Tech’s collaborative approach, the result is a long-term asset that supports both their daily operations and mission readiness.

Aviation-Compliant Audio Architecture

Technical Solutions

To meet Hangar 254’s strict operational and regulatory demands, Crunchy Tech delivered a distributed PA system built for rigor, resilience and control. Every component was handpicked and painstakingly placed to overcome the hangar’s tough acoustics.

System Component Technology/Equipment Role in Project
Loudspeaker Deployment 36 high-power full-range pendant loudspeakers Delivered even SPL coverage and intelligibility across all three zones
Amplification & Processing 4-channel / 4 kW power amplifier, multi-I/O DSP Provided headroom, EQ, delay tuning, feedback suppression and preset recall
Wireless Audio Input 2 lavalier and 4 handheld wireless microphones Enabled flexible audio capture for briefings, ceremonies and tours
Mounting & Infrastructure FAA-compliant pendant rigging, integrated cabling Ensured safe, interference-free installation clear of aircraft paths

Strategic acoustic modeling set the foundation. High-headroom amplification ensured power without distortion. Zone-based DSP control gave the system flexibility to adapt to any operational need. This led to a resilient, scalable solution that delivers crystal-clear sound and full safety compliance no matter the scenario.

Precision Design for a Mission-Critical Space

Implementation Methodology

We started with detailed acoustic modeling to lock in the best speaker placement and zone configuration. The desired result was even coverage without creating disruptive echoes.

Installation was rendered with the utmost care. Work schedules were planned to avoid interrupting maintenance or impeding flight-line activity. FAA-compliant rigging and cabling were installed to perfection. All equipment was suspended clear of aircraft movement paths while keeping sightlines clean.

Close coordination with base personnel happened at every step from concept to commissioning. The client couldn’t be happier that the system measured up to every operational goal and passed inspection on the first review. It now provides simple, intuitive controls for daily utilization.

Improved Safety and Operational Readiness

Results and Impact

The upgraded PA system has markedly refined the way Hangar 254 communicates. Quotidian operations and special events now run with clear, reliable sound. Speech intelligibility reaches from one end of the hangar to the other. Safety instructions, operational updates and ceremonial addresses are heard and understood in every zone.

Reverberation and echo, once major obstacles, have become under control. Precise tuning and zone-specific EQ have produced a balanced acoustic environment notwithstanding a space dominated by reflective metal surfaces. Wireless mics give teams the freedom to run multiple events concurrently without interference. Preset configurations let staff reconfigure the system in mere seconds for maintenance, drills or formal ceremonies with zero manual re-patching.

Fundamentally, our client walked away with nothing short of a dependable, aviation-compliant audio solution. One that underpins the base’s mission while making day-to-day communication faster, safer and more efficient.

Delivered to Military Standards

Finishing the Project On Time

The Hangar 254 project at Pease Air National Guard Base exemplifies Crunchy Tech’s ability to carry out high-caliber, aviation-compliant audio systems under unbending requirements. Conscientious planning, detailed acoustic design and laser focused installation kept the project on schedule. Above all, the system passed all FAA and base safety inspections on the very first review.

Pairing military-grade audio technology with a profound understanding of the client’s mission, the 157th Air Refueling Wing now has an extraordinary communications tool as dependable as the airmen who use it. It’s a high-stakes project that we’re beyond honored to have accepted and accomplished.
