What is the function of the bone in the middle ear?

Answer 1

These are responsible for transferring and amplifying the vibrations from outer ear to inner ear

Answer 2

The three bones of the inner ear are designed to pick up sound waves from the ear drum and send the signals to the brain for interpretation. It is similar to the ear piece of a telephone receiver.

Answer 3

The Ossicles are three bones in your middle ear, which are individually called the Malleus, the Incus and the Stapes. More commonly they are called (respectively) the Hammer, the Anvil, and the Stirrup, because they superficially resemble these common items.

The function of these bones is to act like an amplifier for hearing. The Malleus (or Hammer) is in direct contact with the eardrum, a thin skin membrane that a) keeps water and other things out of your ear, and b) serves as a receptor for vibrations of the air which we interpret as sound.

The Malleus is also in contact with the Incus (or Anvil) and as the Malleus moves from those air-vibrations, it, too, articulates and increases that motion, finally relaying it to the Stapes (or Stirrup). The total mechanical advantage is more than 20 times the original movement.

This amplification is needed because the hearing mechanism is actually hydraulic, not pneumatic. Air movement is not adequate on its own to allow you to hear very well. (See the Cochlea for an explanation of the hydraulic system responsible for hearing, since that was not part of this question.)

If the Ossicles are dislocated due to a blow or trauma to the head, hearing can be reduced to less than 10% of normal. As well you may have noticed that if you listen to loud sounds, such as a rock concert, you feel "deaf" afterward for a while. This is due to a self-protection mechanism called the Stapedius Reflex, which temporarily disconnects the ossicles from the cochlea to prevent permanent damage.

Sadly, this doesn't work with constant abuse, such as high volume levels in music earphones. Gradually you will kill parts of the cochlea at various frequencies (14,000 Hz and above, then 7,000 Hz, then 3,000 Hz, then generally across all the sound spectrum until you are deaf). So as a warning, moderate your sound levels so you don't spend you life saying "Eh? What was that you said?"

Answer 4

to help the movement of the ear

Answer 5

The bones of the middle ear act as amplifiers.
