The fleshy part of ear, the pinna, collects the sound. The sound wave then travels through the auditory canal which funnels the sound to the ear drum causing it to vibrate. The ear drum then amplifies the sound by vibration of bones. It is in the middle ear where sound energy is converted into mechanical energy. The cochlea in the inner ear converts the vibrations into electrical impulses before sending signals to the brain. The brain then interprets the impulses as sound.

∙ 12y agoyour ear hears sounds through a wall because of basic physics. when a noise is made, the air particles move. the particles then transfer the engery they received onto another particle. this process continues till you can hear the sound (till the particles reach your ear) you can hear though a wall because the particles in the wall absorb the motion and transfer that motion onto other particles passing the sound through.

But the sound could be faint. If you need to listen through a wall, I might want to use a contact mic and amplification device, such as one found at http://www.listenthroughwalls.com/.

∙ 8y agoSound is a form of vibration that can pass through the air and some solid objects (like a wall).
We see by light waves which can't pass through most solid objects (like a wall).
A wall can be made of a substance through which light waves can pass (transparent or translucent), such as a glass wall. Walls in many public buildings are made of glass.

∙ 14y agoThe ear is the sense organ that picks up sound waves from the surrounding air and turns them into nerve impulses that can be sent to the brain. The sound waves carry lots of information - language, music, and noises - all mixed up together.. The task of the ear is to turn the signals in these waves of bouncing air molecules into electrical nerve signals, while keeping as much of the information in the signal as possible. (Then it's the brain's job to sort the signals and make sense out of them.) It's not easy to turn one kind of signal into another kind without losing information, but the ear is well designed for the task.
When something vibrates, the vibrations can travel as waves through solids, liquids, and gases. Even animals that have no ears can often feel these vibrations. But in order to understand language and hear music, the brain has to be given more information than just "there'"s a vibration". It needs to know the frequency and amplitude of all the waves that the ear is collecting. Interestingly,, the ear sends this information to the brain very accurately by turning the sound waves in the air (vibrations in a gas) into vibrations in bones (solid), and then into waves in a fluid in the inner ear (a liquid), before they become (electrical) nerve signals. This might seem like a lot of unnecessary translation,, but it allows the sense of hearing to be both sturdy and very sensitive.

What difference does it make if the sound is increased to an ear?
Because of your ear lobe you can hear the sound of low amplitude.
How do we hear sound?
You use a very complicated ear brain system, which is not fully unterstood yet.
Could a person hear if one of the bones in the inner ear did not vibrate?
The person would not have lost their ability to detect sound (that is located in the inner ear). However, the ear mechanism would no longer work as it should and the person would not be able to hear properly as the sound would not be transmitted to the inner ear.
What is the strange Hum sound people claim to hear?
People who hear a humming, a ringing, or a pulsation may have tinnitus or an ear infection.
What is an ear?
An ear is an sensory organ of the body. It helps us to hear sound. The ear is composed of the external ear (which is visible) and the internal ear. The external ear or the pinna is a flap of cartilagenous skin that aids in the collection and direction of sound waves into the inner ear. The inner ear has several parts which is beyond the scope of this answer but the main parts are the cochlea, vestibule and the ear drum. Sound waves directed inwards fall on the ear drum and then are carried inwards in the form of vibrations that the cochlea and the vestibule conduct onwards to the brain through special auditory nerves and hence there is perception of speech.
How do you hear sound through the ear?
when you hear things, its really sound waves. the sound waves enter your ear, then it vibrates the ear drum.
Can sound energy pass through gas?
Yes, sound energy can propagate through gas ( that's the reason we can hear as sound energy travels through the ear to the human ear.)
If sound travels faster through a solid why can't you hear through solids?
In fact, sound does travel faster in solids than in liquids, and faster in liquids than in air. Also, we canhear through solids, but not very well. And it doesn't have anything to do with the speed of sound in the material. Let's look at what's going on.If sound originates in air on the other side of a wall, the sound must impinge on the wall to be transmitted through it. Some of the energy is reflected and some is absorbed, so that doesn't leave much to come through to where we might be listening. Also, you can hear better with an ear to the wall. But if the sound originates in the solid wall, you can hear it better, and can hear it very well with an ear pressed to the wall. This is because the solid will propagate it better (as well as faster) than it would travel in a liquid or in air.You might recall the old Indian trick of putting an ear to the rails to listen to find out if a train was coming. The sound is conducted in the solid rails (even with the spacing between sections) better than through the air. These people didn't know why this was so, but they knew that it was a fact.
What is the roar that you hear when you place a seashell next to your ear?
The roar that we hear when we place a seashell next to our ear is not the ocean, but rather the sound of blood surging through the veins in the ear.
How does putting your ear to the ground help you hear better?
Hearing is a result of vibrations. The sound waves move through the air and vibrate your ear drum. The vibrations are translated by the brain as familiar sounds. Similarly, walls and doors resonate to the same sound waves and act like giant ear drums. By placing your ear to the door, you are effectively able to "transfer" those vibrations from the door (or wall) to your ear and hear, more clearly, what is happening on the other side.
How can you hear a sound?
with your ear
If you cover your ears and hum what is the sound travelling through brain?
Undetectable - the sound you hear travels through the bones of your skull to the inner ear - where all sound is detected.
How does music from your iPod reaches to your ear?
The sound that comes from headphones are electronic pulses sent through the wire and reach your ear drum, which is vibrated and transformed into the sound that you hear.
When you put a shell to your ear how comes you can here the sea?
It is not the sound of the sea that you can hear when you put your ear to a shell, it is echoes of the sound of blood circulating around your head and through your ears.
What is a use of ear?
It is to hear sound
What occurs when sound waves don't pass through the outer to the inner ear?
You don't hear anything. They don't actually have to get there through the outer ear. If your ear is plugged, or if your 'tympanum' (ear drum) is broken, the vibrations can conduct through the bone that you feel behind your ear. But they do have to get to the inner ear somehow. If vibrations don't reach the cochlea in the inner ear, then you don't hear anything.
How is sound technology used in hearing aids?
they have a speaker in the hearing aid so that old dudes can hear through there ear that cant hear
