Sound travels from a source as a series of compressions and rarefactions in the air (sound waves). These waves enter the ear canal and cause the eardrum to vibrate. The vibrations are then transmitted through the middle ear bones to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain via the auditory nerve.

Why can light travel through outer space but sound cannot?
Light is able to travel through outer space because it does not require a medium to propagate, unlike sound which relies on particles to transmit vibrations. In the vacuum of space, there are no particles for sound waves to transfer energy through, so sound cannot travel.
How do you hear sound?
Sound waves enter the ear canal and cause the eardrum to vibrate. These vibrations are transmitted through the middle ear bones to the inner ear, where they are converted into electrical signals by hair cells. These signals travel along the auditory nerve to the brain, which then processes them as sound.
How far can sound travel in space between astonauts?
Sound waves require a medium to travel through to propagate from point A to point B. In space there is no such medium, so sound does not travel in space.
Why is it impossible for sound to travel through outer space?
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
Is there sound in outer space?
No. Sound is a waveform made by the compression and expansion of something called a 'medium'. Usually the medium is air. Sound is caused by vibrations passing through the air. The vibrations cause the air to expand and compress in waves from the source of the sound until it hits our eardrums and transmits the vibrations to the drum, into the ear and to the brain where we recognise it as something we call 'sound'. Of course, sound can travel through other media including water (as in echo sounding) or even in solids (try placing your ear to the end of a broomstick held on a vibrating engine - the sound is really amplified as it passes through the stick). In the vacuum of space, however, there is no air or any other medium, and therefore sound cannot travel. Light can travel through space because light is a waveform that is part of the electromagnetic spectrum (which includes radio waves, microwaves and x rays) and electromagnetic waves do not need a medium in which to travel. The absence of sound in space is often forgotten in cheap science fiction movies where an alien spaceship is exploded and you hear the loud bang. In real life this would never happen. The best depiction of space and the absence of sound in it is in Arthur C Clarke's 2001: A Space Odyssey directed by Stanley Kubrick. Although it is one of the greatest science fiction movies of all time, it was criticised because of periods of silence during the 'space' scenes - but of course this was a factually accurate depiction as opposed to the cheap sci-fi 'B' movies where enemy ships explode in a flash of light and a huge bang.There is no sound in outer space. Sound actually travels as pressure waves through air, and since air does not exist in outer space, there is no sound.
Why do you hear the sound with your right ear before your left ear?
The difference in hearing the sound with your right ear before your left ear is due to the time it takes for the sound waves to travel from the source to each ear. Sound waves travel faster through air than through the bones in your skull, which causes a slight delay in hearing the sound with the ear furthest from the source.
How far did sound travel to your ear?
Sound can travel around 1,125 feet per second in air. The distance that sound travels to reach your ear depends on the source of the sound and your proximity to it.
What dose the ear canal do?
helps travel sound into your ear
What are the prerequisites of sound?
The prerequisites of sound are a source of vibration, a medium for the sound waves to travel through (such as air, water, or a solid material), and a receiver to detect and interpret the sound waves, such as an ear or a microphone.
How does sound get from its source to you?
Waves carry sound energy from the bell to the ear.
What is required to produce any sound?
To produce any sound, you need a source of vibration, a medium for the sound waves to travel through (such as air, water, or solids), and a receiver (such as the human ear) to detect and interpret the vibrations as sound.
How do sound waves travel from the harmonica to your ear?
They don't
What three kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, then the middle ear, before reaching the inner ear where they are converted into electrical signals that travel to the brain through the auditory nerve.
Would sound waves traveling through the outer ear travel faster or slower than those traveling through the inner ear?
Sound waves would travel faster through the outer ear than through the inner ear. This is because the outer ear consists of less dense air, which allows sound waves to travel more quickly. In contrast, the inner ear is filled with fluid, which is denser and slows down the speed at which sound waves travel.
How does sound travel in the air for us to hear?
The sound waves travel by vibrations, which are then percieved by the canals deep in your ear
What three things are needed to hear a sound?
In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.
How does the sound travel in your ear?
Sound waves enter the ear canal and cause the eardrum to vibrate. These vibrations are transmitted through the three small bones in the middle ear, which amplify the sound. The vibrations then travel to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for processing.
