In the Canal Hearing Aids Review
An In-the-Canal hearing aid (ITC) is custom molded to fit the
outer portion of the ear or not as deeply as a completely-in-the-canal
hearing aid.
The in-the-canal hearing aid is less visible but most designs may not fit persons with smaller ears. The ITC though allows the person to use a telephone quite easily.
Many brands nowadays have features that allow some adjustment on the settings, which would be difficult in a completely-in-the-canal hearing aid.
In-the-canal hearing aids improve mild to moderate hearing loss among adults.
There is a smaller variant to the regular in-the-canal hearing aid. It is called the half-shell. Being of smaller size, it is custom molded to fit the bowl-shaped area of the outer ear.
The user will be able to control the volume of a half-shell. Many are designed with directional microphones. As with its smaller size, it fits most ear sizes.
The half-shell is appropriate for persons experiencing mild to moderately severe hearing loss.
