A Barbastelle makes a metallic buzz sound.
Light travels faster (much faster) than sound.
It is called echolocation.
A bat uses clicks called echolocation. The sound waves bounce off whatever that certain species of bat feeds on. ( Bugs, fruit etc...) The bat's excellent hearing picks up that sound wave that bounces back which helps it find the exact location of it's prey.
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!
A bat can tell how big an insect is based on the intensity of the echo. A smaller object will reflect less of the sound wave, and so will produce a less intense echo.The­ bat can sense in which direction the insect is moving based on the pitch of the echo. If the insect is moving away from the bat, the returning echo will have a lower pitch than the original sound, while the echo from an insect moving toward the bat will have a higher pitch. This difference is due to the Doppler effect

A short A typically makes the sound "æ" as in "cat" or "bat." It is a brief, clipped sound produced by a quick movement of the tongue and jaw.
The word "bag" has a short vowel sound. The "a" in "bag" makes the short /æ/ sound like in "cat" or "bat."
"Bat" contains a short vowel sound. The 'a' in "bat" is pronounced as a short vowel sound.
Bats use sound by sending a sound wave to the object or prey that is going to approch,the sound wave bonces of of the prey and goes back to the bat. The sound wave that goes back to the bat tells the bat how far away the bat is and how fast it is approching the bat.
Yes, the word "flash" has a short "a" sound as in "cat" or "bat."
Yes, the word "bat" has a short vowel sound. The 'a' in "bat" is pronounced as /æ/.
The word "hat" has a short vowel sound. The vowel sound is "a" as in "cat" or "bat."
No, the word "bat" does not have a long A vowel sound. It has a short A sound, as in "cat" or "hat."
No, "crab" is not a long vowel word. The letter 'a' in "crab" makes a short vowel sound, as in the word "bat."
In the word "scarf," the letter 'a' is considered a short vowel. It makes the short /æ/ sound, as in "cat" or "bat."
There are different noises off a wooden bat that will tell a good fielder what the hit is going to do. The sound will be different for a pop or a drive The sound will rebound of the outfield walls and tell you where the hit is aimed or headed. It takes years to develop the ear to be a great fielder.
