Vibiscus provides SilentFlow, an AI‑controlled active acoustic absorber that cancels low‑frequency noise inside HVAC ducts while maintaining less than 0.5% pressure loss. The compact, modular units are ten times smaller than traditional silencers and can be retrofitted into existing ductwork without affecting airflow, offering real‑time monitoring and remote diagnostics for facility managers and HVAC engineers.

Problem
Low‑frequency noise generated by HVAC fans, extractors, heat pumps and other ventilation equipment travels efficiently through ducts, creating persistent hum, vibrations and cross‑talk that degrade comfort in industrial, commercial and residential environments. Conventional passive silencers are bulky, cause pressure loss, and often cannot attenuate frequencies below 300 Hz, leaving many installations unable to meet noise‑control requirements.
Solution
Vibiscus offers SilentFlow, an AI‑driven active acoustic absorber designed for integration inside ducts and ventilation paths. The system uses embedded sensors and real‑time digital signal processing to generate counter‑phase acoustic energy, cancelling low‑frequency noise without adding significant resistance to airflow. Its compact, modular design is roughly ten times smaller than traditional silencers, allowing retrofits in existing ductwork with minimal space and no additional pressure drop. The product is CE‑marked, third‑party tested, and available in bulk for large‑scale deployments. Vibiscus also provides a full acoustic diagnostic service that analyses site‑specific noise sources and delivers customized mitigation recommendations.
Target Audience
Primary customers are facility managers, HVAC engineers and building owners in industrial plants, commercial real‑estate, hotels, laboratories, transportation (trains, tunnels) and residential complexes seeking low‑frequency noise mitigation without compromising ventilation performance.
