Every sound you hear comes to you in waves. They start from a vibrating object, like guitar strings, vocal cords, lightning shaking the air, and creating thunder! The number of waves that reach you in a second is the frequency. Its measured in hertz. The more of those waves you sense, the better your hearing is. For example, octopuses can't hear at all, but they can still pick up vibrations of 400 - 1, 000 Hz.
Elephants have a wide range: between 17 - 10, 500 Hz. They can even hear the sound of approaching clouds! Humans have a typical range of 20 - 20, 000 Hz anything higher than that is considered ultrasonic. Where you stand will depend on your age. Cows hear almost 2 times better than humans do, sensing a range of 23 - 35, 000 Hz! Btw, they say cows produce more milk when listening to classical music! So let's find out how different animals hear and whos got the best hearing in the animal kingdom! Date: 2022-04-19
