Acoustic Rainbow Emitters · ARE Technology
Engineering Perception.
Shaping Sound.
Aurallius develops geometry-driven acoustic technologies that reshape how sound propagates through space—enabling systems to operate beyond perceptual detection.
Approach
Sound Isn't Just Heard.
It's Experienced.
Traditional approaches focus on reducing sound at the source—often at the cost of weight, power, or mechanical complexity. Aurallius takes a fundamentally different approach: engineering how acoustic energy moves through space and how it is perceived.
Not suppression.
We redirect acoustic energy directionally rather than absorbing or cancelling it at the source.
Not attenuation.
We shape the spatial distribution of sound to reduce perceptual detectability along observer vectors.
Geometry-driven.
Passive, power-independent structures designed for integration with existing platforms.
Flagship Technology
A New Class of Acoustic Control
Acoustic Rainbow Emitters (AREs) use geometry-driven design to reshape how sound travels. Instead of relying on suppression or power-intensive methods, AREs passively redirect acoustic energy—reducing perceptual impact while maintaining system efficiency.
Directional acoustic control
Manages dominant tonal components away from likely observer vectors through passive geometry.
Reduced perceptual detectability
Designed to achieve operationally relevant reduction in perceived acoustic signature.
Passive, low-power implementation
No active cancellation or power draw. Integration-constrained design for real platform constraints.
Platform-agnostic integration
Designed to accommodate aerodynamic and mass penalties relevant to small UAS platforms.
Applications
Built for Real-World Systems
Autonomous Systems
Enable less detectable drone operations in urban and BVLOS environments without sacrificing performance margins.
Defense & National Security
Support low-observable platform design and reduced acoustic signatures for mission-critical operations.
Urban & Environmental
Targeted acoustic management for smarter, more livable built environments and regulated airspace.
Industrial Systems
Improve acoustic performance in robotics and advanced manufacturing without adding system complexity.
