Sound waves enter your ear canal, vibrate the eardrum, and travel through tiny bones in the middle ear. The cochlea in the inner ear contains thousands of hair cells tuned to different frequencies. These hair cells convert vibrations into electrical signals sent to your brain. High-frequency hair cells are most vulnerable to damage from aging and noise exposure.
| Species | Range (Hz) | Visual |
|---|---|---|
| Human | 20 – 20,000 | |
| Dog | 40 – 60,000 | |
| Cat | 48 – 85,000 | |
| Dolphin | 40 – 160,000 | |
| Bat | 1,000 – 120,000 | |
| Elephant | 16 – 12,000 |
Elephants can hear infrasound below human range, while bats and dolphins use ultrasonic echolocation far beyond our hearing.
