Full description
How’s your hearing? Learn your Hearing Numbers—the softest sound you can hear in each ear—with an app created by the Johns Hopkins Bloomberg School of Public Health. Then use your Hearing Numbers to protect your hearing and hear better. Track your hearing to know how it changes over time and encourage others to know their hearing. Take charge of your hearing wellness! Hearing Numbers can be as low as -10 or as high as 100 decibels, or dB. The higher your Hearing Numbers are, the louder sounds will need to be for you to hear them, and the harder it will be to hear and communicate in noisy places. Requires headphones, a quiet space, and about 5 minutes to complete. No advertising, in-app purchases, or product recommendations. The app tests the noise level around you, measures your hearing levels at four frequencies in each ear, and provides your Hearing Numbers. Share the Hearing Number app and encourage your friends and family to learn their Hearing Numbers. Re-check your Hearing Numbers from time to time and review previous results to track how your hearing changes over time. Learn more about the Hearing Number and how to use it at app.HearingNumber.org. This app is created by the Johns Hopkins Bloomberg School of Public Health, seeking to empower people to know their hearing—millions at a time. Disclaimer This hearing wellness app does not constitute medical advice or diagnosis. You should consult with a health care provider for questions related to your hearing or if you are experiencing any of the following: ear pain or ringing, dizziness, ear drainage or a sense of something in your ear, sudden or fluctuating hearing loss, injury or deformity to your ear, or worse hearing in one ear (i.e., your right and left Hearing Numbers are different by more than 10 dB).
