The Problem
Legacy workflows are slow, expensive, and poorly suited to in-situ evaluation.
Conventional reverberation chamber results according to ISO 354 are difficult to reproduce, expensive to obtain, and highly likely to differ from how the installed acoustic absorber performs in practice.
Slow to execute
Scheduling, setting up a large specimen, and performing many source-receiver-pair measurements are too slow.
Limited reproducibility
Results can vary across facilities and often fail to reflect the real behaviour of the installed surface.
The Solution
A practical new approach to in-situ surface impedance and absorption measurement.
ATLAS combines calibrated hardware with physics-informed AI to deliver fast, repeatable, trustworthy results from in-situ measurements, developed through academic research at Technical University of Denmark (DTU).
Hardware
Calibrated Microphone Array
A purpose-built measurement platform for acoustic characterization tasks where repeatability and data quality matter.
- The measurement model accounts for scattering from the array body.
- Stepper-motor-controlled positioning reduces operator error and improves repeatability.
- Built to move advanced acoustic methods from research into day-to-day engineering workflows.
Software
Physics-Informed Neural Network
ATLAS software combines acoustic measurements with physical equations to quickly estimate the acoustic properties of a surface in terms of surface impedance and absorption coefficient, which are essential input data for acoustic simulations.
- Physics constraints guide inference instead of relying on black-box pattern matching alone.
- Measurement and inference complete in under one minute.
- Outputs include impedance, absorption, and clear indicators for faster decisions.
Sub-minute workflow
Fast measurement and inference for rapid iteration.
Non-destructive
Evaluate installed surfaces without cutting, moving, or destroying them.
In-situ
Designed for the real acoustic environment, not only for the reverberation chamber.
Research to workflow
Advanced methods for practical engineering use.
Product
ATLAS Single Layer Array
A dedicated microphone array for in-situ measurement of surface impedance and sound absorption. Available in two microphone configurations: 16 (4x4) or 9 (3x3) microphones. Designed with portability in mind, the array comes with a 4-inch loudspeaker with integrated amplification, powered via USB by a power bank that doubles as a tripod leg. The array system currently connects to a computer via USB, with wireless capability planned for 2026.
- Evaluate surface impedance with greater confidence.
- Bring advanced measurement capability into practical field and product workflows.
- Connect measurement hardware and software interpretation in one system.
ATLAS Single Layer Array is coming soon, bringing acoustic diagnostics, and fast exporting into one workflow.
