👂 Hearing age

How high can you still hear? Hold each button to play a pure tone from 8 up to 18 kHz, mark what you can hear, and get your estimated “hearing age” — the natural loss of high frequencies with age. Use headphones for a fair test.

Hold ▶ to play — then mark ✓ heard or ✗ not heard.

⚠️ For fun & reference — NOT medical audiometry (which measures dB HL per ear at clinical frequencies). Age mapping follows the well-known presbycusis pattern: ~18 kHz audible under ~20y, ~16 kHz under ~30, ~15 kHz under ~40, ~14 kHz under ~50, ~12 kHz under ~60. Results depend heavily on hardware: laptop/phone speakers often cannot reproduce >15–16 kHz at all — use decent headphones, moderate volume, a quiet room.
