Ventilation systems are indispensable in modern buildings. They regulate air quality, maintain healthy environments and ensure thermal comfort. Yet, for many professionals, one problem remains unresolved: noise. The constant hum of fans, the turbulence of airflow and the resonance of ductwork can generate sound levels that disrupt concentration and, indeed, comfort. At this point, the air duct noise silencer becomes essential. Traditionally, silencers rely on passive materials to absorb sound or on active noise cancellation (ANC) to counteract noise with additional signals. But these methods come with limitations. Vibiscus has developed an innovative alternative, one that redefines how noise can be controlled inside air ducts. Want to know more? Read this post.
At first glance, a silencer might appear to be a static component, simply absorbing part of the noise as air flows through. But Vibiscus approaches the problem differently. Our solution is based on a network of microphones and mobile membranes capable of dynamically modifying the acoustic properties of the surrounding air.
The principle is simple but very smart: instead of generating a counter-noise, as ANC systems do, or relying on thick layers of absorbing material, Vibiscus creates an adaptive absorbing surface. As air passes through, the noise is absorbed and dissipated, leaving the airflow free of unwanted disturbances.
This innovation provides three distinct advantages. First, our system is compact and modular, making it easy to integrate into a wide range of air ducts, regardless of their geometry or complexity. Traditional silencers require significant space, while Vibiscus adapts to existing installations without compromise.
Second, our solution is energy-efficient. Unlike ANC, which constantly generates an additional signal, Vibiscus works with the properties of air itself, requiring far less power to deliver superior results.
Finally, it is intelligent. By integrating artificial intelligence into its design, our air duct noise silencer constantly analyzes the noise environment and adapts in real time. This ensures consistent performance, even when operating conditions change, such as variable airflow rates or evolving duct configurations.
Noise control in ventilation has traditionally relied on two approaches: passive silencers and active noise cancellation. While both have their merits, they also carry significant drawbacks.
Passive silencers, for instance, use absorbent materials to reduce sound levels. They can be effective in certain frequency ranges, but their efficiency drops sharply for low-frequency noise, which is often the most disturbing. They also tend to be bulky, requiring space that is not always available in modern building designs.
Active noise cancellation, on the other hand, generates a sound wave that cancels out the original noise. While powerful in theory, it is highly sensitive to duct geometry and airflow dynamics. Its effectiveness decreases in complex configurations, and it consumes more energy due to the constant production of counter-noise.
Vibiscus has positioned itself at the intersection of these two methods. Our technology absorbs and dissipates noise rather than masking it or relying solely on passive layers. This makes it adaptable to complex ductwork, while maintaining a high level of energy efficiency.
For building managers, engineers, and acoustic consultants, the benefits are tangible:
Choosing Vibiscus is not simply choosing another silencer. It is choosing a new generation of air duct noise silencer, one that anticipates future needs in sustainability, health, and performance.
Traditional silencers use fixed absorbing materials or ANC technology. Vibiscus uses adaptive membranes controlled by AI, making it both more flexible and more effective across a wider range of frequencies.
Yes. Its modular and compact design allows for easy integration into a variety of duct configurations, including complex geometries where standard solutions struggle.
Absolutely. Unlike ANC systems, Vibiscus does not produce additional sound. By working with the properties of the airflow, it reduces noise with minimal energy consumption.
The technology is suitable for all types of structures: office buildings, hospitals, residential complexes, hotels, and industrial facilities. Anywhere air ducts are present and noise is a concern, Vibiscus can bring measurable improvements.
No. Our system is designed to maintain airflow quality and efficiency. Noise reduction is achieved without compromising ventilation performance.
