Most people with hearing loss can benefit from hearing aids. Just as there are different types and degrees of hearing loss, there are different hearing instruments with a wide range of functions and features to address a variety of individual needs. 

Here is a brief summary of the most popular types and styles of hearing aids available today. 

• Completely-In-the-Canal (CIC)                        
• In-The-Canal (ITC)                        
• In-The-Ear (ITE)                        
• Behind-The-Ear (BTE)

Completely-In-the-Canal (CIC) hearing instruments
This is the smallest type of hearing aid available and it is almost invisible in the ear. All the components are housed in a small case that fits far into the ear canal. This takes advantage of the ear's own anatomical design and ability to collect sound naturally.

CICs are custommade for each ear; however, these hearing aids are restricted to people with ear canals large enough to accommodate the insertion depth of the instrument into the ear. Also, the CIC style uses a very small battery that requires good manual dexterity. This type of hearing aid is not suitable for people with severe hearing losses.

In-the-Canal hearing instruments (ITCs)
A little bigger than the CIC, the ITC hearing aids also fit far into the ear canal. Canal hearing aids use a slightly larger battery than the CIC style. This style is used for mild to moderate hearing losses.

In-the-Ear hearing instruments (ITEs)
These hearing aids can be used for a wider range of hearing losses. Due to their larger size, ITEs can accommodate larger sound amplifiers and more features such as a telephone switch. They are also easier to handle for many people.
