The eardrum needs to move only a fraction of a billionth of a meter for us to hear a quiet sound. The movement of the eardrum triggers a chain reaction in the middle ear and inner ear that eventually signals the brain to perceive the sound.

What causes the eardrum to vibrate and how does this process contribute to hearing?

The eardrum vibrates when sound waves hit it, causing tiny bones in the middle ear to move. These vibrations are then converted into electrical signals that are sent to the brain, allowing us to hear and interpret sounds.


Why you can hear sounds better in air then you can underwater?

Sound moves faster and further in water than air, so it would seem like it must have something to do with the receiver. I'm guessing, but I'd guess it's because the eardrum evolved to hear sounds in air. Underwater you don't hear using the eardrum, you hear by way of bone conduction which apparently doesn't let you hear normal sounds as well as the air/eardrum method.


How does magnetism help you hear recorded music?

In simple terms - the music is converted (from an analogue or digital source) into electricity. The electricity passes down the headphone's wires to the speakers. A magnet in the speakers reacts to the strength of the electrical signal to move a small diaphragm. The movement of the diaphragm sets up vibrations in the air between the speaker and your ears, which is then detected by your eardrum. Your brain interprets the air-movement as sound.


When you hear sounds do the molecules of air move from the place where the sound began all the way to your ears?

No, when you hear sounds, the vibrations from the source of the sound travel through the air as waves of pressure. These waves cause the molecules in the air to vibrate, but the molecules themselves do not travel from the source of the sound to your ears.


Is sound a object?

Sound is not an object; it is a form of energy that travels through a medium, such as air, water, or solids. Sound is created by vibrations that move through the medium, stimulating our ears and allowing us to hear it.

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 is the eardrum like a musical drum?

Both the eardrum and a musical drum vibrate when struck, producing sound. The eardrum converts sound waves into vibrations that are transmitted to the inner ear, where they are interpreted as sound. Similarly, a musical drum produces sound when its surface is struck, causing vibrations that create sound waves.

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.


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 does the ear drum move with a low pitch sound?

With a low-pitched sound, the eardrum moves more slowly with gentle vibrations. The larger surface area of the eardrum allows it to capture more of the low-frequency waves and transmit them to the inner ear for processing.


How far can you hear a ticking clock?

This depends entirely on how well a person hears. Some people will not hear the ticking of a clock if they are standing right next to it, while others will hear it in the next room or beyond if it is quiet enough.


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...
