Reducing industrial noise is a critical issue for many companies today, whether for acoustic comfort, regulatory compliance or energy efficiency. Industrial environments concentrate multiple noise sources whose emissions can quickly exceed acceptable levels. But beyond mere annoyance, structural noise can also impair the performance of installations, hinder internal communication and increase the risk of accidents.
Facing these problems, the market has long relied on two traditional methods: passive silencers, which are bulky and often limited in the high or low frequency ranges, and noise reduction systems, which are complex and energy-intensive. Today, manufacturers are looking for more compact, modular solutions capable of meeting the diverse acoustic requirements of modern environments. That’s why Vibiscus offers today a revolution: a compact industrial noise reduction device capable of absorbing and dissipating noise without increasing space requirements.
Industrial noise is rarely the result of a single source. Indeed, it generally consists of a mixture of frequencies, vibrations and turbulence, transmitted both through the air and through structures. Ventilation systems, even if they are essential for temperature regulation and air qualit, are among the primary culprits behind this nuisance. The passage of rapid airflows through angled ducts, grilles or turbines generates sound turbulence that propagates throughout the building.
Production machinery further amplifies this phenomenon. Moving mechanical systems create complex harmonics, sometimes difficult to attenuate with conventional solutions. Furthermore, space constraints in modern industrial environments can make it impossible to install traditional passive silencers, which, while effective, are bulky.
Companies must also contend with stricter regulatory requirements, particularly regarding workplace noise, an higher demands for acoustic comfort and energy efficiency challenges, as conventional attenuation solutions sometimes reduce airflow or increase energy consumption.
It is therefore becoming necessary to adopt a compact industrial noise reduction device without relying on the energy-intensive limitations of a traditional passive noise reduction system. And so, you can choose Vibiscus!
The innovation developed by Vibiscus stems from a simple idea: to offer a technology capable of replacing traditional passive and active solutions, while maintaining a minimal footprint. Our compact industrial noise reduction device is a modular unit that is easy to integrate into ventilation ducts or various industrial infrastructure components.
Unlike a conventional silencer, Vibiscus does not rely solely on fibrous materials or internal chambers designed to dissipate sound. And unlike Active Noise Cancellation (ANC), it does not produce any additional sound intended to cancel acoustic waves. The approach is radically different.
The Vibiscus compact industrial noise reduction device behaves like an augmented acoustic material, based on an array of microphones and moving membranes. This device modifies the acoustic properties of the air in real time to create a dynamic absorbing surface capable of precisely targeting problematic frequencies. The air passing through the module thus has the noise absorbed and dissipated, without loss of flow rate or the addition of bulky systems.
This modular architecture allows for an integration into a wide variety of ducts, an adaptation to existing geometry and a finely tuned acoustic response according to the targeted sound spectrum. Vibiscus therefore offers a compact, precise, and extremely efficient solution, particularly suited to environments where space and energy efficiency are critical.
Our compact industrial noise reduction device works with a combination of onboard microphones, movable diaphragms and integrated artificial intelligence. The operation follows several complementary steps and the first is the acoustic field analysis. Microphones distributed throughout the module continuously capture the sound frequencies passing through the duct. Unlike a simple static measurement, the system analyzes the dynamics of the noise, its composition, its intensity and its variations with airflow.
On this analysis, the movable membranes modify their behavior to adjust sound absorption. They move with millimeter precision to reshape the internal surface and optimize noise dissipation based on detected frequencies.
The goal is not to neutralize noise by phase cancellation, as with ANC, but to capture and dissolve it, like a highly advanced acoustic material. Energy efficiency is significantly improved, since the system does not generate sound and consumes much less energy.
Yes. Its modular design allows it to be integrated into the vast majority of industrial ventilation circuits and HVAC networks, even in complex geometries that are insufficiently covered by traditional passive silencers.
Passive silencers rely on a large volume and conventional absorbent materials. Our compact industrial noise reduction device, on the other hand, uses hybrid active technology with moving membranes that offers targeted absorption in a much more compact format.
ANC generates an opposing sound to neutralize noise. Vibiscus, on the contrary, emits no sound: it absorbs and dissipates noise using a controlled acoustic surface. It is therefore more energy-efficient and more stable in complex environments.
