Once sound enters the ear canal it impacts on the tympanic membrane (The ear drum) its here in the middle ear that sound sound pressure is converted in to mechanical energy. Attached to the tympanic membrane are 3 bones (the smallest in your body), the malleus, the incus and the stapes (or the hammer, anvil and stirrup), these bones are responsible for two things, they are able to regulate the amount of sound coming in to the ear by expanding and contracting the tympanic membrane to protect the ear (although theres around a 100ms delay). They're also responsible for transferring these vibrations to the cochlea in the inner ear through the oval window. Put simply, the cochlea is filled with a watery liquid known as perilymph which moves in relation to the vibrations coming through the oval window. The perilymph then stimulates the thousands of little hair cells (which are 'tuned' to recognise a particular frequency), which convert the energy once again from mechanical to electrochemical impulses before being passed to the auditory nerve and to the brain for further processing.
Sound enters your ear through vibrations, and are usually funnelled into you ear by the pinna which is the flap of skin at the top of your ear- the part that you can see. These vibrations then continue down the ear canal, and the ear drum vibrates (the ear drum is a thin layer of tissue) the vibrations having been made larger by the force of the ear drum vibrating, and the then the sound travels through the ossicles, into the liquid in the snail shell-shaped cochlea, and the-nerve generating hairs combined with the nerve cells of the cochlear nerve send impulses to the brain.
When you first hear a sound, it goes through your outer ear and then through your ear canal. It passes the anvil, stirrup and the hammer (I'm not sure if it goes through) and through the cochlea which goes to the nerves *gasp* which goes to your brain.

What happens when bone marrow enters the brain?
A Whole Eternity!
What happens to the speed of the sound and the light as it enters the plastic?
Depends on the type of plastic.
What parts in the ear assist in the ability to hear a sound wave from the time the sound enters the ear until it reaches the brain?
The auditory canal to the eardrum then the auditory nerve sends it to the brain for interpretation.
What part of brain is used to process sound?
The auditory cortex, located in the temporal lobe of the brain, is primarily responsible for processing sound. Sound information enters the brain through the auditory nerve and is then processed in the auditory cortex, where it is interpreted and recognized as different types of sounds.
Does sound go through your ears?
Yes, sound is recognized by the brain through your ears. When you hear a sound, it enters the ear canal to the eardrum. The eardrum causes small bones to vibrate, which causes tiny hairs to send signals to the brain.
What happens to a sound wave when it enters a denser medium?
When a sound wave enters a denser medium, its speed decreases and its wavelength also decreases while the frequency remains the same. This causes the sound wave to bend towards the normal line at the boundary between the two media.
What is the order in which the sound approaches and enters your nervous system and is interpreted by your brain?
Ear, thalamus, primary audiotry cortex, and auditory assocition cortex
What happens to sound energy once it enters the mouthpiece of a telephone?
Once sound energy enters the mouthpiece of a telephone, it is converted into electrical signals by a microphone. These electrical signals are then transmitted through the telephone wire to the earpiece at the other end, where they are converted back into sound waves that can be heard by the listener.
How does sound travel from a loud speaker to your ear?
Sound leaves the speaker in the form of a wave, through the air, and enters your year, where the eardrum picks up the vibrations of the wave and sends a signal to your brain which interprets the vibrations as sound.
What happens when light enters polarizing filter?
what happens when light enters a polorizing filter?
What happens in your brain when you reflexively plug your ears because of a loud or unpleasant sound?
Nothing really, this is a reflex response and your brain is made aware of it.
What happens when sound vibrations bend hairs on cochlear?
When sound vibrations cause the hairs on the cochlea to bend, this activates sensory cells which then stimulate nerve cells to send signals to the brain. The brain processes these signals as sound, allowing us to hear.
