Better Speech Clarity.
Without Raising the Volume.
Novaural's patent-protected technology isn't limited to hearing aids. It can be applied to any consumer audio device with adjustable frequency output — from AirPods and wireless earbuds to headphones, AR/VR headsets, and audio-enabled eyewear.
Volume Isn't the Answer
Millions of people struggle to understand speech through their earbuds — not because they need hearing aids, but because their ears have subtle frequency gaps that a simple volume increase cannot fix.
The Volume Trap
When speech sounds unclear, the natural reaction is to turn up the volume. But this amplifies all frequencies equally — including those you hear perfectly well, exposing healthy frequencies to potentially damaging sound pressure levels over time.
Hidden Listening Effort
Even when you "can hear" through your earbuds, your brain is constantly working harder to fill in the gaps at frequencies where your perception is weaker. This unconscious effort causes listening fatigue — making calls, podcasts, and music draining over extended use.
A Growing Gap
Age-related hearing changes begin as early as your 30s, typically affecting high frequencies first. Most people don't notice — they unknowingly compensate with volume, gradually damaging the frequencies that still work well.
Frequency-Specific Intelligence, Not Volume
Instead of amplifying everything, Novaural identifies exactly which speech frequencies you struggle with — and adjusts only those, leaving healthy frequencies untouched.
Per-band adjustment example — only deficit bands modified
Our technology evaluates your speech sound discrimination — the ability to tell apart similar-sounding speech sounds like "thin" vs "sin" or "fan" vs "van" — at specific frequencies using a quick, scientifically validated test.
Based on your results, the system generates precise, per-frequency adjustments that can be applied to the equaliser of any compatible device. Only the frequencies where you show a measured deficit are modified — typically by just 1–3 dB.
The result? Speech becomes clearer without any overall volume increase. Your brain no longer needs to strain to decode what it's hearing, and your healthy frequencies remain protected at their natural levels.
The Benefits of Frequency-Specific Audio
A subtle, intelligent adjustment to how your device delivers audio can have a transformative impact on your daily listening experience.
Safer Listening
Protect the hearing you have
- ✓ No need to increase overall volume to understand speech
- ✓ Healthy frequencies remain at their natural, safe levels
- ✓ Prevents gradual noise-induced damage from daily over-amplification
- ✓ Adjustments are bounded by acoustic safety limits built into the algorithm
- ✓ Especially critical for users who listen for extended periods (commuters, remote workers, students)
Reduced Listening Fatigue
Less effort, more clarity
- ✓ When speech frequencies are at the correct level, your brain processes audio with less effort
- ✓ Reduces the unconscious strain of "filling in the gaps" for weak frequencies
- ✓ Calls, meetings, and podcasts feel less tiring over long sessions
- ✓ Improved comfort during all-day earbud use
- ✓ Benefit compounds over weeks and months of daily use
Objective, Not Subjective
Unlike generic "sound profiles" or EQ presets based on preference, Novaural's adjustments are derived from a psychophysically validated speech discrimination test — measuring actual perception, not opinion. Two listeners with identical hearing tests may need different adjustments based on how their brain processes speech, and our technology captures this.
Works Across Languages
The system adapts to the phonemic structure of any language via interchangeable configuration files. Whether you listen predominantly in English, Spanish, Mandarin, or any other language, the evaluation and adjustments are calibrated to the specific speech sounds that matter in your language.
Works With Your Existing Devices
Any consumer audio device with adjustable frequency bands — AirPods, Galaxy Buds, Sony WF-1000XM, over-ear headphones, bone conduction devices, AR/VR headsets — can benefit. The technology adapts to whatever equaliser architecture your device uses, from 5-band to 20+ band systems.
Backed by Science, Protected by Patent
Built on peer-reviewed audiology research and the Jakobson-Halle-Fant distinctive feature system. The methodology — from speech sound evaluation to frequency-specific output modification — is covered by our 47-claim patent application filed with UKIPO.
Not Just for Hearing Loss
You don't need a hearing aid to benefit from smarter audio. Novaural's technology helps anyone whose perception across the speech frequency spectrum isn't perfectly uniform — which includes most adults over 30.
Adults 30+
Age-related high-frequency changes begin in your 30s. Most people don't notice until it becomes significant — but the subtle gaps already affect clarity through earbuds.
Remote Workers
Hours of video calls through headsets leads to fatigue. When speech frequencies are properly balanced, meetings feel less draining and comprehension improves in noisy environments.
Students & Learners
Listening to lectures, language courses, or audiobooks through earbuds becomes clearer and less tiring, especially when studying in a second language with unfamiliar phonemes.
Music & Audio Enthusiasts
Beyond speech, frequency-specific calibration can reveal details in music you've been missing — vocal harmonics, hi-hat sibilance, subtle instrument textures — without over-amplifying the mix.
Gamers & VR Users
Spatial audio and in-game dialogue clarity in AR/VR headsets and gaming headphones benefits from a frequency profile matched to your actual perception, not a generic curve.
Frequent Travellers
When using noise-cancelling earbuds in planes, trains, or busy environments, personalised frequency adjustment makes speech-based content (calls, podcasts, audiobooks) clearer without needing unsafe volume levels.
Works With Any Audio Device
Our technology is device-agnostic. If your device has adjustable frequency bands — whether via a built-in equaliser, firmware API, or companion app — it's compatible.
Wireless Earbuds
AirPods, Galaxy Buds, Sony, Bose, and any TWS with EQ control
Headphones
Over-ear, on-ear, open-back, closed-back — wired or wireless
AR / VR Headsets
Meta Quest, Apple Vision Pro, or any headset with audio output
Audio Eyewear & More
Smart glasses, bone conduction devices, and any host device with adjustable audio
