How does the sound get from the outer ear to the inner ear?

Answer 1

Soundwaves travel through the air and the ear flap directs the sound into the ear canal. the ear canal takes it to the ear drum, the ear drum vibrates, hitting the hammer which moves the anvil then, the stirrup acts like a piston.

Sound is caused by oscillations in matter. The frequency, tone, ect. are based on the material, it's mass, it's density, and many other factors. Oscillations in matter, which are cause by a force or transfer of energy, travel as waves and as such need a medium in which they transfer. If someone were to slam their hand on a desk; this is what would happen: The forced vibration in the table would attempt to travel in all directions and the wave would hit every particle all around it. Once the energy from the eave has been transfered it need to transfer elsewhere and so it hits another particle which hits another which hits another in a domino like effect. The ear is designed to picked up these vibrations in the ear from every angle and so it does. The energy flows into the ear and hits the ear drum, which transmits the sound through bone called "ossicles". The energy continues to flow down into the middle ear . The Cochlea, which is fluid filled, receives vibrations from the ossicles and the air in the middle ear. The fluid is thus set into motion from different angles and the mechanical energy from the fluid flows against thounsands of tiny hairs (or hair cells). The hair cells then convert this mechanical energy into electrical energy via neurotransmitter (chemical) to nerve cells (Vestibular cochlear nerve). The information from the elctrical pulses are picked up by the brain and the brain determines the frequency, pitch, volume, tone, timbre, distortion level, and direction of sound. The brain then reproduces the sound in your head. Amazing really...

Also, the fluid in the Cochlear also gives you a sense of balance. When you turn your head to one side; the fluid flows to on side which displaces the tiny hairs. Try turning your head to one side and you'll feel what I'm talking about.

Answer 2

Sound waves travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted through three small bones in the middle ear called the ossicles (hammer, anvil, stirrup) to the cochlea in the inner ear, where they are converted into electrical signals that the brain can interpret as sound.

Answer 3

• Your middle ear translates sounds that enter your outer ear into vibrations that can be... Ruptured eardrum.

Answer 4

Sound waves enter the ear and come into contact with the thin skin on the eardrum, vibrating it. This vibration continues to the attached bones; malleus, incus and stapes. It then goes to a drumlike structure, called the "round window", on the cochlea, causing the fluid inside to move, which then causes the hairs inside to move. When they are moved, signals are sent to the brain and interpreted.

Answer 5

Sound is amplified by the eardrum which vibrates when the wave hits it. Them the vibrations are transmitted to the three small bones, the hammer anvil and stirruo. These bones amplify the vibrations and then send energy to the fluid-filled cochles in the inner ear, the vibrations reach hair-tipped cells that generate signals that are then sent to the brain.

Hope this helped!

Answer 6

The human ear is composed of three parts, The outer, inner and middle ear. Sound of any sort travels first through the outer ear, then to the middle ear and on to the inner ear, where we hear it and sometimes even feel it. Each part of the ear performs a job that allows the next part of the ear to do its job better.

Answer 7

Usually the sound comes as sound pressure waves from outside the head, goes through the ear canal and hits the ear drum.

Answer 8

Shape of your ear lobe is designed in such a way that the sound waves get concentrated to ear drum.

Answer 9

it passes threw the wind and enters the inner ear

Answer 10

Through the Ear Canal.
