聴力テスト＆耳年齢テスト：あなたの耳は何歳？

◆ Test your hearing at home! Check your hearing easily with this simple-to-use app. Measure your hearing ability from 125 Hz to 8000 Hz and view the results in an easy-to-read graph. ◆ Ear Age Test As we age, we tend to lose the ability to hear high-frequency sounds. Sounds around 17,000 Hz, often called "mosquito tones," are typically only audible to younger people. This test plays sounds up to 20,000 Hz to check how high you can hear, and estimates your "ear age." Are your ears younger than your actual age?
