Auditory Illusions

📋 What it is

Ears and brain can be fooled too — sounds that seem to rise forever or words you "hear" differently.

🗣️ Coach says

Illusions aren’t only visual. AUDITORY illusions fool the ears and brain: a tone can seem to rise forever (yet never gets higher), and the same sound can be "heard" as different words depending on what you expect or see. Just like vision, hearing is the brain interpreting signals — and it can be tricked.

🧠 Memory hook

Auditory illusions fool the EARS+brain too: forever-rising tones, words you hear differently by expectation.

😂 Giggle

Why did the gymnast study physics?
She wanted to find her center of gravity — it kept tipping her off!

😲 Whoa!

The "Shepard tone" is a sound that seems to climb higher and higher endlessly — it’s used in films to build unending tension, but it never actually rises in pitch.

✅ Quick check: Do illusions only trick our eyes?

Say your answer out loud first — then reveal.
