You see the cricket ball hitting the bat first and then hear the sound?
Light travels faster (much faster) than sound.
Do ultrasonic bat repellers work?
Studies have proven that ultrasonic sound does not reverberate. This means that once the ultrasonic sound hits a surface, it disappears. Any animal that is living in any kind of crevice, such as a bat, they won't even hear the sound at all. ADDED. That's not correct: you have misunderstood "the studies" and the basics of sound. Ultrasound will not normally give rise to reverberation because as its frequency rises its absorption losses through the air rise, on top of the attenuation by distance. Some surfaces will absorb sound, but generally ultrasound is easily reflected from any suitable surface, and the bat will hear a sound within its own hearing frequency-range. This is how bats navigate and hunt!
When is the energy transmitted by a sound wave considered no longer to be sound?
It is tempting to answer this by saying that the energy will no longer be sound when it cannot be heard. But it may be able to be detected by another non-human animal - a dog or bat, for example. Sound is a form of mechanical energy. And it can exist at levels outside our ability to hear it, or to even detect it with equipment. The answer in physics is this: the energy transmitted by a sound wave will no longer be considered to be sound when its amplitude is zero. If this is an end run at the question as to whether or not a tree falling in the forest still makes a sound if no one is there to hear it, nice try. Once more: sound is a form of mechanical energy. If something like, say, a tree falls in a forest, a portion of the energy released will appear as sound. And the sound is there whether anyone is around to hear it or not.
Which bat makes a'metallic buzz 'sound?
A Barbastelle makes a metallic buzz sound.
What kind of echo does a bat hear from a object moving away from it?
frequncy
How come you hear a sound when you bat your eyelashes?
The human bodies make many sounds that are so quiet, they are often unnoticeable. The sound comes from the skin of the eyelid lightly touching the eyeball.
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.

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

Why can't humans hear the sound of a bat?
Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.
How a bat hear?
Bats hear with their ears and echolocation; it picks up vibrations and then waits for them to come back to the ear. See the related question below.

Why are children more likely to hear bats than adults?
Because children can hear higher frequencies, and a bat sound is usually very high pitched. A child may also not be able to hear it, if the bat has a particularly high voice. In theory, children can hear a maximum high pitch of 20,000Hz. This is only if the child's hearing is perfect, which, in most cases, it isn't. Basically, what I'm trying to say, is that as you get older, your ability to hear high pitched sound gets worse.
You are used to bat with yet I never get a hit you are near a ball yet is never thrown?
eyelashes
How bats use sound to help them fly?
Bats use sonar to sense their surroundings. Sonar works by the bat making a high-pitched call and listening to the echo from nearby objects. So bats definitely do make a noise when they fly. Also, a bat's wings are not designed for stealth, so even if you do not recognise a bat's sonar call, then you would hear the wings beating when a bat flies close to you. In reality, nobody really thinks about the noise of bat's wings because of the noisy call.
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.
