Batting our eyelashes does not produce enough force or movement to create sound waves that can travel through the air and be perceived by our ears. Sound is created when an object vibrates and causes air molecules to move, which our ears can detect. Eyelash movements are too gentle to create these vibrations and hence do not produce any sound.

How come you do not hear a sound when you bat your eyelashes?
Blinking is a rapid movement and the displacement of air caused by it is minimal, which is why we don't hear a sound when we blink. The movement is also highly localized to just the eyelids, so the sound produced, if any, is likely too subtle to be detected by our ears.
How come you don't hear a sound when you bat your eyelashes?
Blinking your eyelids is a gentle and quick motion, so it doesn't create enough force to generate sound waves that can be heard. Additionally, the distance between your ears and your eyes is relatively long, making it harder for any sound produced to reach your ears.
You see the cricket ball hitting the bat first and then hear the sound?
This observation is due to the physics of sound travel. The speed of light is much faster than the speed of sound, so you see the ball hitting the bat before you hear the sound of the impact.
What kind of echo does a bat hear from a object moving away from it?
A bat would hear a weaker and more stretched out echo if an object is moving away from it, as the sound waves would take longer to return. This could indicate to the bat that the object is further away.
What kind of echo does a bat hear from an object moving away from it?
A bat would hear a Doppler-shifted echo from an object moving away from it. This means the frequency of the echo would be lower than the frequency of the sound wave emitted by the bat. The bat's brain is able to interpret this change in frequency to understand the direction and speed of the object.

How come you hear a sound when you bat your eyelashes?
When you bat your eyelashes, the movement creates a small amount of turbulence and friction in the air, which can produce a soft rustling sound that is amplified due to the close proximity to your ears. The sound is very subtle and typically only audible in a quiet environment.
What is 1 fun fact of a bat?
Bats cannot see, so they use sound that humans can't hear to receive signals about what is in front of them.

Name a flying mammal which makes sounds which humans cannot hear?
a bat

What can hear the best?
The bat. It can "hear" sound waves produced by it's own voice. The shape of the waves change when they bounce off obstacles, so the bat literally navigates by it's ears.

A bat would hear a weaker and more stretched out echo if an object is moving away from it, as the sound waves would take longer to return. This could indicate to the bat that the object is further away.
What is a short a sound?
The short \a\ sound is "ah" as opposed to the long \a\ where you hear the sound of the letter. Examples: fat act jam gas bad pad had bat cap dad cat
What kind of noise does a bat make?
Bats use echolocation, emitting high-frequency sounds that humans cannot hear to navigate and locate prey. These sounds can vary in frequency and pattern depending on the species and the situation.
