Fit Hearing

Will itc and and cic hearing aids fit any ear?
I wear glasses so I will need a cic or itc type hearing aid. Are these type of hearing aids universal in fit? I don’t see how the ear canal could vary greatly from person to person.
Actually your ear shape is about as unique as your finger print. I read a news article in England one time about a burglar who was caught because he used to always press his ear against a window of a house he was about to burgle. They used his ear print to identify him!
The ear canal is similarly unique. There are two bends in every ear canal which can go in different directions for each person. Then there is the diameter and more specifically shape of the canal that varies too.
During my career I have probably looked in over 12,000 ears! They are all different.
A CIC fits deep inside the ear and so even the slightest imperfection in shape will make it seem very uncomfortable. An ITC fits further out of the ear and of all aid styles is probably the one with the closest to a universal fit since it touches less of an ear than most styles.
All quality hearing aids are made to match the exact shape of an ear by taking an impression of the ear, much like a dentist takes an oral impression for certain procedures. This allows the factory to produce a hearing aid that fits perfectly.
An ill-fitting hearing aid will not only cause a lot of discomfort, but will also be prone to whistling (feedback) and even falling out of the ear.
