Where silence meets innovation

AI-optimized noise reduction technology revolutionizes noise control for a quieter, healthier and energy-efficient world.

The problem

Low frequency noise remains one of the hardest unsolved problems in real-world acoustics. It propagates far, penetrates structures, and crucially travels through ducts as an efficient waveguide, spreading noise across a building and even outdoors through exhaust and air discharge points.
Persistent hum, vibrations, cross-talk between rooms, and a “background discomfort” that survives conventional treatments.

A site can become a neighborhood nuisance simply through fans, AHUs, extractors, and exhaust outlets, even when the installation looks acceptable on paper.

Breakthrough

Passive solutions (foam, mineral wool, bulky silencers) rely on thickness, length, and available space. In the low end, they become large, hard to integrate, and often trade performance for pressure drop, airflow constraints, and footprint. Traditional active noise control can work, but deployment at scale is often painful: external sensors, deep system integration, site tuning, maintenance, reliability constraints.

Vibiscus brings active control into an industrial product logic: compact, repeatable, easy to integrate, and built for real world HVAC deployment.

Active acoustic absorber

SilentFlow is an active noise absorber engineered to target low frequencies inside ducts, where passive approaches typically plateau.
