Technology – The Science Behind the Future of Hearing
Introducing Free-Field Audiology
For decades, audiology has measured hearing through headphones and pure tones — a method that isolates the ear but ignores the complexity of real-world sound.
Hearoll Medical’s head-mounted free-field system changes that. It surrounds the listener with a calibrated ring of speakers, each precisely positioned to recreate everyday acoustic environments.
“Our system doesn’t only test ears — it tests hearing.”
— Martin Sørnes, Founder & CEO
The Ring-of-Speakers System
Imagine six ultra-precise speakers forming a ring around the patient’s head — placed at ±45°, ±90°, ±135°, and 180°. Two deliver speech, while four generate controlled background noise, building a true-to-life 3D sound field.
The result is a test that finally mirrors the world we actually hear.
True-to-Life Sound Field – Speech and background noise come from multiple directions to replicate natural listening conditions.
AI Calibration & Signal Control – Built-in algorithms maintain precise, repeatable testing standards across clinics.
Compact, Portable Design – A comfortable, head-mounted format replaces bulky speaker setups.
Seamless Integration – Works with existing audiometers and test protocols, ensuring smooth adoption in any clinic.
Fully Validated & Traceable – Complies with international calibration and medical device standards.
Next-Generation Speech-in-Noise Testing
The Hearoll system revolutionizes how speech-in-noise testing works — simulating real acoustic challenges that people with hearing loss face every day.
- Directional Hearing Assessment – Measures how patients detect and understand speech from different angles. (Version with more speakers, this can result in training therapies for directional hearing)
- Dynamic Noise Environments – Mimics shifting sound conditions for advanced diagnostics.
- Data-Driven Hearing-Aid Fitting – Enables clinicians to fine-tune devices by recreating noise environments the client describes as problematic, clinically.
The outcome: faster fittings, better diagnostics, and more natural hearing results.
AI and Data Integration
Hearoll’s platform is designed for the age of intelligent audiology. Every test produces anonymized performance data that powers the future of predictive hearing care.

Redefining the Standard
Hearoll’s vision is to replace outdated, tone-based methods with a scientifically validated, globally standardized test that captures the richness of real hearing.
We’re preparing regulatory submissions, multi-center validation studies, and collaborative trials with hospitals and universities to establish the next international benchmark for audiology.
