How To Make A Hearing Aid

My mother broke one of her hearing aids and needs to get a new one. We took her to the shop in Tunbridge Wells for a cast of her inner ear to be made.  The audiologist took a scoop of green putty and a scoop of yellow putty and kneaded them together,  put a tiny sponge in my mother's ear canal to protect the ear drum and then injected the putty mixture after it with a big fat syringe.  She told my mother not to talk because moving the jaw distorts the shape of the ear. The mixture took about five minutes to dry.

Humani nihil a me alienum puto.
