Heating, ventilation and air conditioning systems (HVAC) are the invisible lungs of our buildings. They regulate the air we breathe, ensure comfort, and maintain optimal thermal conditions throughout the year. Yet behind this indispensable function hides a recurring challenge: noise. The constant hum of fans, the vibration of ducts, or the turbulence generated by airflow can quickly turn into a source of discomfort. With this in mind, would you like to reduce the noise emitted by your ventilation or air treatment systems? If so, you may want to consider using our technology which rethinks traditionnal active noise cancellation solution for HVAC systems. Find out all about it here.
Noise generated by HVAC systems is often underestimated. Unlike sudden or isolated sounds, HVAC noise is continuous, diffuse and omnipresent. Its impact is therefore insidious, gradually affecting comfort and even health.
The sources of this noise are multiple. Fans and compressors generate mechanical vibrations that travel through ducts, turbulent airflow creates whistling or humming and poorly designed or aging systems amplify resonance effects. In open-plan offices, schools, hospitals, or residential complexes, these background noises can accumulate and form a soundscape that is far from neutral.
The consequences are well documented: loss of concentration, increased fatigue, stress, and even sleep disorders. In professional environments, noise also reduces productivity and increases the risk of errors. From a regulatory perspective, many countries have reinforced acoustic requirements for HVAC installations, particularly in sensitive sectors such as healthcare or education.
Traditional solutions exist but show their limits. Passive silencers or absorbent materials can reduce certain frequencies but remain bulky and sometimes incompatible with modern architectural constraints. Active noise control (ANC), which consists of adding a counter-noise, is effective in very specific cases but requires high energy consumption and is often limited to simple geometries.
This is where Vibiscus offers a new approach, one that rethinks active noise cancellation for HVAC systems in a smarter and more adaptable way.
Vibiscus was born from a conviction: noise is not inevitable. By combining acoustic science, fluid mechanics, and artificial intelligence, our company has created a solution that stands apart from both traditional passive treatments and conventional ANC systems.
The principle is as simple as it is powerful. Instead of adding sound to cancel noise, Vibiscus modifies the acoustic properties of the air itself. A network of microphones continuously analyzes the noise environment. This information is transmitted to mobile membranes, which adapt in real time to create an absorbent surface. The air passing through the system is thus “filtered” acoustically, leaving behind a quieter, more comfortable flow.
This innovation places Vibiscus halfway between two worlds: the robustness of passive materials and the precision of active systems. The result is a noise cancellation solution for HVAC that does not mask noise but absorbs and dissipates it intelligently.
Unlike conventional ANC, which is limited to low frequencies and simple straight ducts, Vibiscus technology adapts to more complex geometries. It can be integrated into a wide range of ventilation ducts without requiring major structural modifications. Its compact and modular design also makes it possible to install it discreetly, even in confined spaces.
The Vibiscus solution is not only innovative in its concept, it also brings tangible benefits for professionals and end-users alike.
The first advantage is energy efficiency. Because the system does not rely on generating counter-noise but on intelligently absorbing existing noise, it consumes significantly less energy than classic active noise cancellation solutions for HVAC.
Another key strength is its intelligent regulation via AI. The noise produced by an HVAC system is never constant. It varies according to airflows, demand, or even equipment wear. Thanks to artificial intelligence, the Vibiscus system continuously analyzes these variations and adjusts its membranes in real time. This ensures stable and precise performance, regardless of operating conditions.
Integration is also a major asset. Vibiscus has been designed to blend seamlessly into existing structures. It can be installed in ducts without requiring significant redesign, making it particularly attractive for renovation projects. For architects and engineers, this flexibility removes one of the traditional obstacles to acoustic treatments: their bulkiness and incompatibility with modern design constraints.
HVAC systems are indispensable, but the noise they generate should not be considered inevitable. The search for an active noise cancellation solution for HVAC has long been marked by compromises: bulky silencers, limited ANC technologies, or partial solutions. Vibiscus breaks this pattern by offering a balanced, intelligent, and efficient technology.
Compact, modular, and powered by artificial intelligence, Vibiscus transforms airflow into a vector of comfort rather than nuisance. By absorbing and dissipating noise rather than masking it, this solution redefines what acoustic control can be in modern buildings.
