NASHVILLE, Tenn. — Discovery Sound Technology (DST) has announced the availability of the latest version of its field-tested Discovery Platform ((dp))™. DST said it combines advanced new audio diagnostics, structured processes, analytics software, and a data-driven approach to enable HVAC service companies to provide proactive predictive maintenance.

According to DST, like most machines, HVAC system components, whether mechanical, electrical, or pneumatic, generally provide ample warning of an impending failure by making identifiable noises that worsen over time. These noises are often generated at higher frequencies in their early stages and above what human hearing can discern. With years of experience, senior HVAC technicians learned to recognize and diagnose many such sounds as they became audible, although most components are nearing the point of complete failure before a service call is even requested. In this old industry paradigm, most service calls were reactive in nature. Also, in this mode, most equipment was repaired or replaced rather than being proactively serviced and maintained.

The Discovery Platform ((dp)) has been in development and field testing for over three years in joint collaboration with early service provider customers. The technology transforms HVAC service from reactive repair and replacement to proactive predictive maintenance, said DST. Because it automates and simplifies many tasks, it helps improve service technician productivity, reduce labor costs, and retain customers.

Key features include:

• Advanced audio sensors — Patented digital ultrasound sensors that technicians use to capture audio recordings of HVAC equipment components at predetermined locations throughout the system.

• Audio file database — A constantly expanding proprietary database containing over 100,000 sound files with “audio matching” technology that compares new recordings to the database for rapid problem identification and intelligent, accurate HVAC diagnostics.

• Analytics — Cloud-based analytics and a suite of reporting modules and tools for professional and consistent site management and customer communication.

• Data-driven — A structured, data-driven approach with back-end database for reliable long-term customer HVAC asset management.
