🔊 What Is Bone Conduction?
Bone conduction is the process of transmitting sound vibrations through the bones of your skull (especially cheekbones or jawbones) directly to the inner ear (cochlea), bypassing the eardrum.
🧠 How It Works:
-
Sound source (like a bone conduction headphone) creates vibrations.
-
Vibrations pass through the bones of the skull.
-
They reach the cochlea in the inner ear.
-
The cochlea converts these vibrations into nerve signals, just like normal hearing.
So you can "hear" without using your outer or middle ear!
🎧 Where It's Used:
-
Bone conduction headphones (for runners, cyclists, swimmers)
-
Hearing aids (for people with damaged eardrums or middle ear)
-
Military and underwater communication devices
-
Google Glass, special helmets, etc.
🧪 Try This Simple DIY Demo:
-
Plug your ears with your fingers.
-
Tap your teeth together or hum — you still "hear" it through your skull.
-
That’s bone conduction in action.
⚖️ Pros and Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Bypasses damaged eardrums | Sound quality is usually lower |
| Keeps ears open to ambient sound | May not be suitable for deep bass |
| Good for outdoor/awareness | Can cause tickling sensation on skin |
