Plasmapanel®
A compact, lightweight panel providing deep-subwavelength ultrabroadband sound control.
Sonexos Plasmapanels leverage our highly-innovative and patented Plasmacoustic Metalayer technology to deliver configurable sound control across a wide frequency range, from several Hz to kHz, in a thin form-factor compatible with a diverse set of applications.
Plasmapanels represent a revolutionary leap forward in the domain of acoustic control. Addressing the challenges inherent in traditional passive sound treatments and active control methods. Plasmapanels offer deep-subwavelength ultrabroadband performance in a lightweight, fully-customisable design.
Advanced Sound Transduction
Plasmapanels feature a patented high-voltage electrode arrangement at their core. This innovative component generates ionised gas particles through corona discharge, whose movements are precisely modulated to create sound waves.
Configurable Active Sound Control
Microphones embedded on the front surface of the Plasmapanel capture ambient sound and transmit this data to an electronic controller. Powered by proprietary software, the controller dynamically adjusts the panel’s output to absorb, reflect, or cancel incoming sound, tuning its response to meet the specific needs of each application. In active absorption mode, for example, the Plasmapanel effectively reduces unwanted noise and reverberation, independent of the sound’s angle of incidence. This ability to control sound precisely ensures enhanced acoustic clarity and comfort within the installation space.
Flexible Design & Installation
Plasmapanels are highly customisable, providing flexibility in form-factor and dimensions tailored to meet the specific needs of each application. Their lightweight, streamlined design ensures easy installation, and their versatile configuration options allow for both standalone and arrayed setups. This adaptability guarantees optimal performance across various spaces, from intimate rooms to expansive auditoriums.
