There are various styles of hearing aids that are available, each with it's own advantages and limitations. The size of the hearing aid that is recommended for you is dependent upon a number of different factors, including the type and severity of your hearing loss, the size and shape of your ears, your manual dexterity and cosmetic issues. The size of the hearing aid, in part, plays a role in the cost of the aid; typically, smaller hearing aids are more expensive. Described below are the styles of hearing aids:
Behind-the-Ear (B.T.E.)
Behind-the-Ear hearing aids fit snuggly behind the outer ear, and curve to conform to the shape of the ear. They can be worn comfortably with or without glasses. The aids secured to the ear with a custom-fit ear mold, which also channels the amplification into the ear canal. B.T.E. aids can fit a wide range of hearing losses, from mild to profound. Because all of the electronic components of the aid are housed behind the ear, and are not exposed to as much body heat, moisture and wax as those that go in the ear, they are typically the most durable style hearing aid. The average battery life for this type of hearing aid is two weeks.
In-the-Ear (I.T.E.)
In-the-Ear hearing aids are custom-made to fit inside the ear, filling most of the visible "bowl" portion of the outer ear. All of the electronic components are housed within the plastic shell of the hearing aid. I.T.E. hearing aids can typically fit mild to severe losses. The average battery life for this type of hearing aid is ten days to two weeks.
In-the-Canal (I.T.C.)
In-the-Canal hearing aids are also custom-made to fit inside of the ear. This style fits deeper inside the ear canal and does not take up as much of the "bowl" portion of the outer ear as do I.T.E. hearing aids. Again, all of the electrical components are housed within a plastic shell that fits down in the ear canal. Because of the smaller size restrictions with this style of hearing aid, it is typically only recommended for individuals with mild to moderate hearing loss. The average battery life for this type of hearing aid is seven to ten days.
Completely-in-the-Canal (C.I.C.)
Completely-in-the-Canal hearing aids are custom designed to fit all of the way down in the ear canal, making them the least noticeable. Because this style fits down inside the ear canal, they can be easily used with the telephone without any special telephone device, can cut down on wind noise and can reduce "echo" sensations. There are, however, several drawbacks due to the small size of this hearing aid; 1) people with very small or curved ear canals may not be able to wear this style due to size limitation; 2) people with manual dexterity issues may have difficulty manipulating the hearing aid; 3) this style is more prone to wax-related breakdowns; 4) this size may require additional appointments for re-casing to achieve a snug but comfortable fit. This type of hearing aid is usually only recommended for individuals with mild to moderate hearing loss. The typical battery life for this hearing aid is five days.
