About Ear Explorer
Ear Explorer follows a sound on its trip through the ear: the outer ear catches it, the ear canal carries it, the eardrum wobbles, three tiny bones pass the wobble on, the snail-shaped cochlea turns it into signals with thousands of tiny hair cells, and the hearing nerve takes it to the brain. Tap each part to learn what it does, then put them in order.
In the Sound lab you change pitch and loudness and watch the sound wave change: faster wobbles make higher notes, bigger wobbles make louder sounds. A higher-or-lower game trains your ears with notes that get closer and closer together. Sounds are kept gentle on purpose.
How loud is too loud? compares everyday sounds in decibels, from a whisper to fireworks, and shows how long each is safe to hear, using the rule that 85 dB is safe for about 8 hours and every 3 dB more halves the time. It teaches the 60/60 rule for headphones and to use ear protection at concerts and fireworks. Not a hearing test.
Best for ages 7+
