Most hearing aids are worn externally. Advances in audiology technology have created hearing aids that are smaller and more powerful than ever before. The models and variety of features is extensive. But all external hearing aids fall into one of these major categories:

  • Behind-the-ear (BTE) hearing aids are the largest hearing aids, but they are also the most powerful. Because the hearing aid rests behind the ear, and is not limited by the size of the ear canal, it can house large and powerful batteries. The hard plastic case sits behind the ear and is connected to a tube in the ear. This is referred to as an “open fit” and solves the problem of a feeling of fullness in the ear that can be caused by wearing hearing aids. There is also a variation where the receiver sits in the ear and is attached by a small piece of tubing. This is referred to as a “receiver-in-canal fit.” The electronic components sit in the case that is worn behind the ear. BTE aids can be worn by children and adults. They are prescribed for mild-to-profound hearing loss.
  • In-the-ear (ITE) hearing aids fit completely inside the outer ear. An earmold is made so the hearing aid fits exactly in the ear. Because children are still growing, this style is not appropriate for children. This style is appropriate for mild-to-severe hearing loss. Because it is not very visible, it is popular with people who are concerned about the appearance of hearing aids. Many ITE aids come standard with a telecoil. The telecoil receives the sound signal directly, instead of coming from the microphone. A telecoil works with most telephones and the FM accessibility systems used by churches, schools, airports and auditoriums.
  • In-the-canal (ITC) hearing aids fit into the ear canal. Because these hearing aids are custom made to fit the ear canal, they are not appropriate for children. A completely-in-canal (CIC) hearing aid is totally hidden in the ear canal. All of the ITC types of hearing aids are appropriate for mild-to-moderate hearing loss. These hearing aids are ultra small. They may be difficult for someone with dexterity issues to insert, remove, and clean. Also, because they are so small, they use very small batteries. The limited power source limits the power of the hearing aid. So, they are not recommended for people with severe to profound hearing loss.

No matter they type of hearing loss you have, your audiologist will help you pick the style that gives you the maximum benefit and provides the features you need.
