Campus-Wide Audio Safety Audits
Our comprehensive audits are designed to give you a complete picture of your intercom and sound system’s performance. Typically completed in one day per building, each audit begins with the creation of a detailed aerial map of your campus to document system locations and layouts.
We then conduct a full walk-through of your facility to locate, spot-test, and evaluate every speaker, horn, and call switch. This process includes verifying intelligibility, coverage patterns, and detecting any acoustic anomalies that may interfere with clear communication. A visual inspection of all inputs, outputs, cabling, and equipment is also performed to identify potential issues before they become critical.
To further ensure accuracy, we carry out a campus-wide audio broadcast test to identify “dead zones” and confirm that all areas receive adequate, intelligible sound coverage. Our team evaluates urgent repair needs and provides written recommendations for corrections, improvements, or upgrades. In addition, we review any local sound systems that may be integrated with your main system, noting opportunities for enhancement or compatibility.
Upon completion, you receive a comprehensive written report outlining current performance, areas of concern, and practical next steps to strengthen your system’s reliability and safety.

We restore and extend the life of aging intercom systems through professional tune-ups. Services include vacuuming, chemical cleaning, testing, and preparing systems for continued use.
