All people should check their hearing from time to time, especially those who are at a higher risk of hearing loss such as adults above 50 years, those working in noisy places, those listening to music at high volumes for long periods of time and those experiencing ear problems. Services for early identification and intervention should be made available through the health system. | Want to connect with hearWHO | Check out our website: https://www.who.int Like and Follow us on Facebook: https://web.facebook.com/WHO/ Follow us on Twitter: https://twitter.com/WHO | Limitations | The accuracy of your test results will depend on the type of headphones you use, as well as the ambient noise level. The results we provide are intended as a first step in testing your hearing. Please always seek advice from a medical professional. 1. If your result from using hearWHO was not favourable, we strongly recommend you obtain a complete hearing evaluation by a certified service provider / medical professional to determine your exact hearing status. 2. Even if your results are in the positive range but you have concerns about your hearing, we encourage you to seek a complete hearing evaluation performed by a certified service provider / medical professional. 3. Whilst the test has a reasonable degree of accuracy, it is only intended as a screening test, with a small proportion of cases that may be incorrectly classified. 4. The WHO and hearX Group will not be held responsible or liable for any results that are incorrect or for your use of the application. 5. hearWHO is only intended for use by persons 16 years of age and above. The test is not intended to be used for children and will not provide reliable results in such cases. 6. A visit to a certified service provider can assist in differentiating between different types of hearing problems. 7. Hearing loss may be caused by obstruction of the outer ear canal from wax, fluid or changes in the structure or function of the middle ear system, and changes in function of the nervous system. 8. Some of these hearing problems can be treated whilst others may be permanent and may need assistive devices. 9. It is important to consult with a certified service provider early; all forms of hearing loss may become more serious is they are left unaddressed.

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? Choose generic and test anyway. You still get a full-spectrum profile. Our preferred devices: • Anker Soundcore Liberty 3 Pro • Apple AirPods® Generation 3 • Apple AirPods Pro® Generation 1 • Apple AirPods Pro® Generation 2 • Apple AirPods Max® • Beats Studio 3 • Jabra Elite 7 Pro • Kef Mu3 • Moondrop Alice • Sennheiser Momentum True Wireless 2 • Sennheiser Momentum True Wireless 3 • Sennheiser Momentum 4 • Skullcandy Crusher 1080 ANC • Sony WF-1000XM4 • Sony WF-1000XM5 • Sony WH-1000XM5 • Technics AZ60 • Technics AZ80 • Technics AZ100 NOTICE FullScale is not designed or intended as a diagnostic or treatment tool for any medical condition, disease, injury, handicap, or disability, and should not be relied on for self-management of health issues. For any hearing-related concern, consult a medical doctor or qualified health professional. FullScale can be used to improve sound personalization, or as a preparatory step before seeing a provider.
