About this app

NEW IN VERSION 2

You asked to try the test without creating an account. Now you can. Version 2 is a complete rewrite, and that was the first thing we changed.

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.
