How high pitch is the bats echo location?

Bats use a wide range of frequencies for echolocation, but they are generally considered to be ultrasonic, meaning they are above the range of human hearing.

Here's a breakdown:

* Human hearing range: 20 Hz to 20,000 Hz (20 kHz)

* Bat echolocation frequencies: 20 kHz to over 200 kHz

So, the "pitch" of bat echolocation can be as high as 10 times higher than the highest frequency a human can hear.

It's important to note that:

* Different bat species use different frequencies: Some bats specialize in high-frequency calls (over 100 kHz) for hunting small insects, while others use lower frequencies (around 20 kHz) for hunting larger prey.

* Echolocation frequency can vary within a species: A bat might adjust its call frequency depending on the environment, target size, and other factors.

Therefore, it's impossible to say definitively how "high pitch" bat echolocation is, as it varies significantly. However, it is safe to say that it is well above the range of human hearing.
