Types of Hearing Aids: Usage and Maintenance Tips


Technological advances in a hearing today allow dispongamos a wide variety of types of hearing aids, in order to meet the needs of each person, especially older adults with hearing loss. Among them we find:

Headphones (BTE)

Hearing_aids1It consists of two parts, an ear mold that is placed inside the ear external and is connected to the hearing aid behind the ear, where the electronic components. The sound reaches the ear mold and from here to the inner ear. It is recommended to use it to people of any age with mild or high hearing loss. As advantages can be indicated its flexibility and ease of adaptation and disassembly, and also is usually very durable.

Open-fit or open-fit

Hearing_aids2It is also classified as retroauricular hearing aid but is smaller than the previous one. The hearing aid is placed completely behind the ear, and inside the ear, only a thin tube is inserted. It is usually recommended to people who accumulate much earwax in the ear because this substance can damage the molds are placed in the ear canal of other types of hearing aid. However, they are used more to resolve problems of mild or moderate deafness.

Intracanal (ITC)

Hearing_aids3They are hearing aids that are made to measure taking into account the size and shape of the patient’s ear canal. They tend to be less powerful than BTEs, because the narrowness of the ear canal does not allow for the design and placement of a wider hearing aid, so they are not usually used in people with severe hearing loss.

Within the channel (CIC)

Hearing_aids4They are even smaller than intracanal hearing aids, and are placed completely within the ear canal. It happens as with intracanal, that its power will depend on the narrowness of the ear canal, although there are already models that cover the needs of people with more severe hearing losses.


Hearing_aids5It can be said that it is a model that combines the retroauticular hearing aid with the intracanal because the earpiece is placed inside the auditory canal housed in a mold made to measure. When placed inside the ear canal there is less chance of feedback or beeping and is much more aesthetic than the auricular.
