What is the useful energy in a whistle?
acoustic energy, when you make sound it is audible because it is in sound waves that move through the atmosphere and into you ear to vibrate your eardrum
When you hear sound do the molecules of air move to where the sound began to your ears?
Yes.
Why you can hear a sound around a corner?
I suggest you play in the bathtub. Sound moves in the same way that waves move on the surface of the water. You will SEE how sound goes round corners.
You hear my sound you feel me when i move but see me you never will?
Earthquake?
Why can you not hear in a vacuum?
Sound waves have to have something physical to travel through, such as air or water. There is nothing in the vacuum for the waves to move in.
Why do earmuffs block sound?
Sound is the movement of air that then moves your eardrum, which allows you to hear. If you are wearing earmuffs, then the air movement doesn't make it to your ears as well, meaning it doesn't move your eardrum as much. This is why it sounds muffled and quiet.

How does a string to make its sound?
It vibrates. The vibrations move through the dtring, then though the air and into your ear. In the ear the eardrum vibrates.

Yes.
Why can the human ear hear all sounds?
1. The outer ear picks up the sound vibrations 2. These sound waves travel through the ear canal 3. The eardrum vibrates and make 3 tiny bones in the middle ear move 4. These bones send these vibrations to the shell-shaped structure called choqlea 5. The sound vibrations make the liquid in the cocheleq move making the hair move back and forth 6. The hair are joined to the nerves and send signals to your brain
How far can you hear a ticking clock?
You can typically hear a ticking clock from about 20 to 30 feet away in a quiet room. The sound may get softer as you move further away, and background noise can also affect how far the ticking can be heard.
What part of the ear vibrates when sound waves strike it?
The sound waves come through the auditory canal and hit the eardrum (or tympanic membrane). The eardrum is connected to the 3 ossicles of the middle ear: the hammer, anvil and stirrup (or malleus, incus and stapes). The eardrum vibrates the hammer, the hammer vibrates the anvil, the anvil vibrates the stirrup and the stirrup vibrates the cochlea in the inner ear which has hair-like nerve endings called cilia that move when the cochlea vibrates. The auditory nerve sends the vibrations to the brain to be interpreted. That's how we hear! :)

Vibrations cause sounds yet if you move your hand back and fourth through the air you don't hear a sound explain?
You can't move your hand fast enough, the lowest frequency sound is about 20 cycles per second, if you could move your hand that fast, you might hear sound.
Which are those animals that move ears to hear sound?
Cats, dogs, rabbits...
How is the eardrum like a musical drum?
it's like a eardrum because in the middle air, these waves make the eardrum vibrate. The vibration of the eardrum move three tiny bones called the hammer, the anvil, and the stirrup.
What do people do when they are blind?
Touch themselves hear them and they will move in the sound thy want to go
