Question

Чому людина не чує звуки які видають кажани?

Answer 1

Ответ:

тому що звуки які видають кажани частотою нижче 20Гц а людина може чути лиш звуки частотою від 20Гц до 20000 Гц

Answer 2

Why Can't Humans Hear the Sounds Made by Bats?

Humans cannot hear the sounds made by bats because bats emit high-frequency ultrasonic sounds that are beyond the range of human hearing. Bats use echolocation, emitting these high-frequency sounds and then listening to the echoes that bounce back to navigate and locate prey in the dark. The frequency range of human hearing is typically between 20 Hz and 20,000 Hz, while bats emit sounds at frequencies much higher than 20,000 Hz, often in the range of 20,000 to 200,000 Hz [[1]].

How Bats' Echolocation Works

Bats emit these ultrasonic sounds through their mouth or nose, and the sound waves travel through the air. When the sound waves encounter an object, they bounce back as echoes. Bats' ears are highly sensitive to these echoes, allowing them to create a mental map of their surroundings and detect the location, size, shape, and texture of objects, including potential prey [[2]].

Conclusion

In summary, humans cannot hear the sounds made by bats because bats use ultrasonic frequencies for echolocation, which are beyond the range of human hearing. This ability allows bats to navigate and hunt in the dark, demonstrating the remarkable adaptations and sensory capabilities of these fascinating creatures.
