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.
The eardrum sends sounds entering the ear canal through the air as sound pressure variations to the cochlea of the inner ear.
Sounds entering the ear canal through the air as sound pressure variations are collected by the eardrum and are sent to the cochlea of the inner ear.
Vibrate with the frequency of the received sound
The use of the ear drum is that the ear drum is the part of your ear mainly used for hearing.
The sound vibrations vibrate the eardrum.Then the vibrating eardrum makes the three tiny bones vibrate and then something else vibrates and then the nerve sends message to brain.
The membrane will move back & forth a little, in synch with the noise.
A tiny bone in the ear which conducts sound from the ear drum to the middle ear.
ear drum
Hearing. They transmit the sound vibrations from the ear drum to the inner ear.
a perforated ear drum
It is called an ear.
to maintain equivalent air-pressure on both sides of the ear drum.
I dont know what the ear drum does that is what i am finding out now
The external auditory meatus is the ear canal that allows sound waves to pass from the external environment to the tympanic membrane (ear drum).
This is the same as asking if you can hear under water and yes, you can hear under water.
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
