Types of hearing aids
There are many types of hearing aids (also known as hearing instruments), which vary in size, power and circuitry. Among the different sizes and models are:
NIH illustration of different hearing aid types.
Body worn aids
This was the first type of hearing aid invented by Harvey Fletcher while working at Bell Laboratories. Thanks to developments in technology they are now rarely used.[citation needed] These aids consist of a case, an ear mold, and a cord. The case contains the amplifier components. The case is about the size of a pack of playing cards and is worn in the pocket or on a belt. The ear mold is connected to the case via a cord. Because of their large size, body worn aids can provide loud amplification. This made them appropriate for profound hearing losses. Today, body aids have largely been replaced by Behind-The-Ear (BTE) instruments.
Behind the ear aids (BTE)
BTE aids consist of a case, a tube and an earmold. The case is small and made of plastic. It fits behind the pinna (ear). The case contains the amplification system. The tube is used to route the sound from the hearing aid case to the earmold. Typically the sound is routed acoustically. Sometimes the sound is routed electrically. In that case, the speaker is located in the earmold instead of in the case. The earmold is usually custom made or made of other pliable fixture that contours to the individuals ear. The color of the BTE components (case, tube and earmold) range from inconspicuous skin tones to bright colors and optional decorations.
BTEs can be used for mild to profound hearing losses. BTEs have several advantages over other types of hearing aids.[citation needed] One advantage is that they tend to be more durable. This is because the electrical components are located outside the ear. This reduces the amount of earwax and moisture that the electrical components are subjected to. Another advantage is that BTEs can be connected to assistive listening devices, such as classroom FM systems. Lastly, if the earmold no longer fits the user, the earmold can be replaced for a fraction of the price of a new hearing aid. BTE hearing aids are typically prescribed for children. This is because children need a durable hearing aid, often need
assistive listening devices, and often outgrow the size of the earmold.
Recent innovations in BTEs include miniature BTEs with thin hair-like sound tubes (see open-fit devices below). These are often less visible than In-The-Ear aids (ITEs). They use a larger vent than other hearing aid types. This keeps the ear canal more open, which allows sound to enter the ear without being amplified. This is helpful for listeners with normal hearing in the lower frequencies. Miniature BTEs are generally used for mild to moderate high frequency losses.
In the ear aids (ITE)
These devices fit in the outer ear bowl (called the concha); they are sometimes visible when standing face to face with someone. ITE hearing aids are custom made to fit each individual's ear. They can be used in mild to some severe hearing losses. Feedback, a squealing/whistling caused by sound (particularly high frequency sound) leaking and being amplified again, may be a problem for severe hearing losses. Some modern circuits are able to provide feedback regulation or cancellation to assist with this. Traditionally, ITEs have not been recommended for young children because their fit could not be as easily modified as the earmold for a BTE, and thus the aid had to be replaced frequently as the child grew.[citation needed] However, there are new ITEs made from a silicone type material that mitigates the need for costly replacements.
Receiver In the Canal/Ear (RIC/RITE)
At a first glance, these devices are similar to the BTE aid. There is however one crucial difference: The speaker ('receiver') of the hearing aid is placed inside the ear canal of the user and thin electrical wires replace the acoustic tube of the BTE aid. There are some advantages with this approach: Firstly, the sound of the hearing aid is arguably smoother than that of a traditional BTE hearing aid. With a traditional BTE hearing aid, the amplified signal is emitted by the speaker (receiver) which is located within the body of the hearing aid (behind the ear). The amplified signal is then directed to the ear canal through an acoustic tube, which creates a peaky frequency response. With a RITE hearing aid, the speaker (receiver) is right in the ear canal and the amplified output of the hearing aid does not need to be pushed through an acoustic tube to get there, and is therefore free of this distortion. Secondly, RITE hearing aids can typically be made with a very small part behind-the-ear and the wire connecting the hearing aid and the speaker (receiver) is extremely inconspicuous. For the majority of people this is one of the most cosmetically acceptable hearing device types.[citation needed] Thirdly, RITE devices are suited to "open fit" technology (see below) so they can be fitted without plugging up the ear, offering relief from occlusion.
