Can You Hear This? Turning a Clinical Hearing Test into a Kids’ Game
2026-06-18 , A113 (capacity 64)

During a professional hearing test for my daughter, I noticed something odd: the technician explicitly instructed her not to raise her hand when no sound was played. That was the moment I realized the test deliberately relies on false positives and false negatives — and that the process itself is surprisingly fragile, especially for kids.

Out of curiosity (and mild parental stubbornness), I decided to recreate the standard clinical hearing test in code, and then explore how it could be improved. The result is a browser-based open source hearing test and a kid-friendly game.
