## Description

Discover your Hearing Numbers with a quick, evidence-based hearing check from the Johns Hopkins Bloomberg School of Public Health. The app measures the softest sound you can hear (in decibels) at four frequencies in each ear, checks ambient noise, and returns easy-to-understand Hearing Numbers so you can track changes over time and take action to protect your hearing.

Requires headphones, a quiet space, and about 5 minutes. No ads, in-app purchases, or product recommendations. Use your results to monitor hearing wellness, encourage friends and family to test, and visit app.HearingNumber.org for more information. This tool is educational and not a medical diagnosis—consult a healthcare provider for symptoms like ear pain, sudden hearing changes, or other concerning signs.
