Beyond Human Frequency - Snapple "Real Fact" #48

Did You Know?

Fact: Cats can hear ultrasound.

Ultrasound is the frequency of sound waves greater than what the human ear can hear (approximately 20kHz). Cats have an approximate hearing range of 45Hz - 64,000Hz compared to 65Hz - 20,000Hz of a human hearing range.
