Casting a piston to the inside of the ear
canal and then removing it is gonna cause
a significant vacuum. Sounds painful, at least.
At worst, a burst eardrum and inner ear
infection? Ewww!
Nope, that's how ear moulds are made for hearing aids, and custom fitted
IEM's. Of course one should probably know what they are doing before
attempting it.
It appears that a critical step is blocking the ear canal with a cotton
ball
that has a thread attached to it so that you can pull it back out easily
and
reliably.
Trevor and Arny, I guess that means there is a large
enough air pocket in the canal that a dangerous level
of vacuum is not attained. This will be what I learned
today.
Until I understood the process a whole lot better than I do, I would retain
the services of professional who is trained and experienced in doing this
kind of thing.
