Yes. You can burst a person's eardrum by striking them near their ear. See related question link.
yes
The eardrum is essentially the membrane of the ear that absorbs sound waves. Since this is essentially skin, it is possible to heal, however if ruptured it can be severe. Delving deeper, the eardrum is a very, very sensitive instrument. It works in a process, and I'd need to know exactly what you mean by "burst and eardrum" to respond.
Once your ears experience of a breaking of the sound barrier it permanetley bursts your ear drums making you go deaf.
Well in your eardrum there is a speaker
No.
Sound begins at the eardrum and ends at the brain.
Too much pressure can rupture an eardrum. For example, I ruptured my brother's eardrum many years ago with one of those pool noodles. We were fighting with them in the pool and I smacked him in the side of the head with it. The force of impact directly over his ear created enough pressure inside of his ear cavity to actually rupture his eardrum. Another thing that can rupture/burst an eardrum is simply sticking something that doesn't belong inside of your ear too deep, physically puncturing the eardrum. Although eardrums can burst, they can also heal. However, the older you get, the more difficult it becomes for your body to repair an eardrum.
The function of the eardrum is to transmit sound and amplify vibration.
Sonic (sound) energy is related to your eardrum.
Sound is transmitted through the air to the eardrum as variations in pressure above and below ambient atmospheric pressure.
The auditory canal allows sound to get to the eardrum.
