FullScale Hearing Test vs EbbChart

A MUSIC-CENTRIC HEARING TEST Conventional hearing tests are built around speech. They check eight frequencies and stop at 8 kHz, because that band is where conversation lives. Music doesn't stop there, and neither do we. FullScale maps your hearing from 125 Hz to 20 kHz at up to 37 frequencies per ear, in about eight minutes. Our proprietary calibration keeps that measurement accurate across a growing list of headphones and earbuds. CORE FEATURES • Pick your resolution: 16-frequency core test, or up to 37 frequencies with psychoacoustic models • Four testing speeds to fit your schedule • Three scientific models (Audiometric, Bark, ERB) • Calibrated for a growing list of headphones and earbuds • Simple guided interface with clear visual results • Unlimited retests YOUR RESULTS • Full-spectrum curve compared against a normal-hearing reference • Traditional 4-point PTA for quick reference • Speech-region results in implied dB HL alongside standard dB • Clear interpretation, compatible with a traditional audiogram • No paywall on your own hearing data HEAR THE DIFFERENCE IMMEDIATELY When the test ends, FullScale builds a hearing-correction preset from your results, and you compare it against the original back to back, on the spot. Most people hear it in the first few seconds. Signed-in tests include 3 ARIA AI credits, enough to generate and audition an AI-refined preset. Additional credits are available if you test repeatedly or want to explore more presets, and credits carry across all Altitude apps. KEEP YOUR CORRECTION WITH ARIA ONE Sign in for your test and your profile follows you into ARIA ONE, our hearing-correction app. • No charge on mobile • Mac and Windows run a free tier, with a 30-day trial of the full feature set Finish the test, install ARIA ONE, and your hearing correction is set up and running. YOUR DATA Your hearing data is encrypted, exportable, and yours to delete. We don't sell it and we don't share it without your direct consent. WORKS WITH OVER 5,000 HEADPHONES AND EARBUDS Put on whatever you already own and start. The app handles the rest. • Preferred devices: 18 models we measured and calibrated ourselves, for the tightest high-frequency accuracy • Community database: thousands more headphones and earbuds from the AutoEq project, searchable in the app • Generic: don't see yours, or don't know the model?
