Want this question answered?
yes it is. I'm going to have it in 3 or so years when I'm eighteen because it might effect my exams, but it is done if the eardrum is permanently perforated like mine by taking a bit of cartilage from somewhere else and putting it on the hole I'm told. Apparently its not the nicest of operations though.
Depending on what caused it, it may either feel like a big relief (eg. if there is a build up of pus inside), or it might not feel anything at all, or it might be very painful.
Non-perforated mean no holes in the object or something like that
because the flap looks like a drum
The eardrum is more like a sensing microphone's diaphragm or membrane.
it's like a eardrum because in the middle air, these waves make the eardrum vibrate. The vibration of the eardrum move three tiny bones called the hammer, the anvil, and the stirrup.
1. Being to close to a loud noises especially loud neighbors. 2. Sticking something in their ear that is smaller than their elbows. 3. by having the ear lobe pulled with great pressure like Edison had done to him.
Perforated metal is used for things like signs and fencing and even metal furniture, like benches. Prominently, perforated metal is used for things like the vents in your home or as some sort of decorative fencing.
It looks like a large perforated cracker.
It isn't
Its a tray that can carry like ladders.
I had a vacuum delivery, and the pain of the baby coming out was like hell on earth.
