Inside your ear/Custom made hearing aids usually come in three different styles depending upon where they sit inside your ear canal. They are usually suitable for mild to severe hearing losses.
CIC (Completely in the canal)- smallest, most discrete although may not be suitable for those with narrow/small ear canals
ITC (In the canal)- still discrete, slightly bigger than CIC with a small part facing out into the ear
ITE(In the ear)- occupies the outer portion of the ear
Over-the-ear type hearing aids include RITE/RIC and BTE styles
Receiver in the ear (RITE)/Receiver in Canal (RIC) is a sleek, small behind-ear instrument with a small receiver in the ear canal. These aids are versatile and suit most individuals with mild to severe losses.
Behind the ear (BTE) is a slightly larger instrument and is suitable for severe to profound losses.
