The ear drum (aka: Tympanic Membrane) has several functions. It helps protect our middle ear space from debris and foreign objects, it connects to the middle ear bones (ossicles) in order to transmit vibrations that enter the ear canal to the middle ear bones.
The ossicles are connected to the fluid-filled inner ear organ (the cochlea). The sound wave vibrations that travel through the tympanic membrane to the ossicles vibrate the inner ear fluid; which helps transmit sound to our brain.
The ear drum is sensitive and can break or perforate due to: Penetration due to a foreign object (ex:Que-Tips jammed too far in the ear canal), bugs and other pests can chew through it (this is why it is GOOD not to clean out wax intentionally; our body makes wax to protect the ear drum), or it can rupture due to fluid in the middle ear space building up from infection (this is why "tubes" are sometimes placed in ear drums of people with recurrent ear infections to help even out the pressure from the fluid to protect the ear drum).
I have observed people with perforated or absent ear drums, and they can still hear, albeit not as well if they did have one, but as long as the middle ear bones are intact, they will still be able to vibrate to sound waves and thus the person can indeed hear. These patients must be careful because they are more prone to infection without the protection of their ear drum.

ear drum
Function of the hammer anvil stirrup?
Hearing. They transmit the sound vibrations from the ear drum to the inner ear.
What is a whole in the ear drum?
a perforated ear drum
Which sense organ contains the drum?
It is called an ear.
What is the function of the eustation tubes?
to maintain equivalent air-pressure on both sides of the ear drum.
What job does the ear drum do?
I dont know what the ear drum does that is what i am finding out now
What is the function of the external auditory?
The external auditory meatus is the ear canal that allows sound waves to pass from the external environment to the tympanic membrane (ear drum).
Can your ear drum function underwater?
This is the same as asking if you can hear under water and yes, you can hear under water.
What is the function of the bone in the ear known as the hammer?
It bangs against what is known as the ear drum and they replicate vibrations and transfer the vibrations to the brain, and that's how you hear. Hope that helped
What instrument can you carry in your ear?
an ear drum!
Where does the sound vibrate in the ear?
ear drum
