there waves that tell sound
Bats emit a type of biological sonar which we call echolocation. They let out a loud, high-pitched sound (often above the range of human hearing) which bounces off any obstacles in its way, and then returns to the bat in the form of an echo. These return waves tell the bat how far away the obstacle is as well as its size and shape. These bats have large ears which are very good at understanding the information brought back to them by the echoed waves of sound.
Amplitude is the maximum displacement of a wave. The amplitude determine the loudness of the sound
Sound is measured in Decibels. This is judged based on the human hearing. You can use a decibel meter to detect how loud a sound is.

Could be a slipping belt. You don't say the make, so difficult to tell. If you know how to access the belt, change it .
If you tap your glass bead on glass it will make a "sharp" sound. If you tap your bead on glass and it makes a "dull" sound, it is most likely not made of glass.
bats make high pitched squeals to find their way around in the dark, they have poor eyesight so the noises bounce back to tell them where things are.
Yes. Without out, comedians (and comediennes) would not be able to tell their jokes. However, unlike helium, it won't make your voice sound squeaky or high-pitched.
They let out a screech that is too high pitched for human ears, and it bounces off objects ,such as insects, when the sound comes back to them they can tell where the object is by how long it took the sound come back to them and how loud it was. apparently they have really good hearing.
Sound can tell you many different things like the type of instrument played or how high or how low it's played
There are a few different methods my good friend but most of the time its feedback and some vibrato. Give it a try.
yes they do if you dont tell them of when they bark. also they have high pitched barks which can be very annoying.
You can tell someone is high just by looking at their eyes. They may be red if eye drops weren't used, even if they were you can look right at the pupils, if they're dilated, chances are they're high.
mainly sound , a 2 stroke has a high pitch tinging noise and a 4 stroke has a deep loud sound
A 2 stroke has a high pitch sound like a weed eater and a 4 stroke is deeper sound.
