Plasmapanel®
Lightweight, fully-customizable panel enabling plasmacoustic metalayer for deep-subwavelength ultrabroadband sound control.
Plasmapanels leverage an innovative 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.
Product Overview
The Plasmapanel features a cutting-edge plasmacoustic metalayer at its core, developed by a patented high-voltage electrode arrangement. This innovative component, comprised of positively charged ions, is modulated electrically to produce sound waves capable of reducing ambient noise and improving the quality of surrounding acoustics.
Advanced Sound Management
Microphones embedded within the panel’s front surface capture ambient sound, relaying this data to an electronic controller. Utilising proprietary software, the controller adapts its output to enable the metalayer to absorb, reflect, or cancel sound according to the requirements of the specific application.
Acoustic Enhancement
Configured for absorption, the Plasmapanel excels in eliminating unwanted noise and reverberation, regardless of its angle of incidence. This unique capability can significantly enhance the acoustics and sound comfort of the environment in which the panel is installed.
Customization and Design
Plasmapanels are highly customisable, offering flexibility in both form-factor and dimensions to suit each application’s specific needs. Their lightweight and streamlined design simplifies installation, while versatile configuration and attachment options support standalone or arrayed use. This adaptability ensures optimal performance in a wide range of spaces, from small rooms to large auditoriums.
