Hearing aids have come a long way since the creation of the first electric hearing aid in 1898. It was the invention of the carbon microphone, transmitters, the digital signal processing chip (DSP), and the rapid development of computer technology that really helped transform the hearing aid to it’s present form. By the late 20th century, digital hearing aids became the standard.

There are a wide variety of types and styles of hearing aids (also referred to as hearing instruments) and they vary in size, power and circuitry. There are about a half dozen hearing aid manufacturers whose products are sold under many, many brand names, some of which you’ve probably heard of on television commercials or seen in big box stores or full service department stores.

According to the FDA (Food and Drug Administration) there is a difference between hearing aids and sound amplifiers. Hearing aids are meant to compensate for hearing loss and are considered a medical device and, thus, regulated by the FDA. Sound amplifiers are for amplifying environmental sounds for consumers with no hearing loss. The FDA does not consider these to be medical devices when labeled for recreational use only. However, certain safety regulations related to sound output levels still apply to these products.

There is no single style of hearing instrument(s) in today’s market place which is the perfect solution for each individual person. Differing degrees and types of hearing loss, lifestyles, associated symptoms, budgets, current technologies, color and other personal preferences all combine to have a significant influence on which hearing instruments offer the best personalized solution for each individual. For that reason, hearing instruments are made in many technological styles and sleek ergonomic designs to address the individual needs of every person. ihearingaids will help narrow down your search to find the hearing instrument which is best for you. The most common styles of hearing instruments include:

Completely-in-the-canal (CIC)

A completely-in-the-canal hearing aid is molded to fit inside your ear canal. It improves mild to moderate hearing loss in adults.

A completely-in-the-canal hearing aid:

  • is the smallest and least visible type

  • is less likely to pick up wind noise

  • uses very small batteries which have a shorter life and can be difficult to handle

  • doesn’t contain extra features such as volume control or a directional microphone

  • is susceptible to earwax clogging

In-the-canal (ITC)

An in-the-canal (ITC) hearing aid is custom molded and fits partly in the ear canal. This style can improve mild to moderate hearing loss in adults.

An in-the-canal hearing aid:

  • is less visible in the ear than larger styles

  • includes features that won’t fit on completely-in-the-canal aids, but may be difficult to adjust due to it’s small size

  • is susceptible to earwax clogging

In-the-ear (ITE)

An in-the-ear (ITE) hearing aid is custom made in two styles — one that fills most of the bowl-shaped area of your outer ear (full shell) and one that fills only the lower part (half shell). Both are helpful for people with mild to severe hearing loss.

An in-the-ear hearing aid:

  • includes features such as volume control and directional microphones that are easier to adjust

  • is generally easier to insert

  • uses larger batteries, which are easier to handle and last longer

  • is susceptible to earwax clogging

  • may pick up more wind noise than smaller devices

  • is more visible in the ear than smaller devices

Behind-the-ear (BTE)

A behind-the-ear (BTE) traditionally consists of a form fitting, colorized, plastic case, with an attached custom fit ear mold. BTE’s have historically been effective in addressing the larger range of hearing loss. The various sizes and stylized cases are typically moisture resistant and enclose the electronics, controls, battery, microphone and speaker. Generally, the case sits securely and weightlessly behind the ear with a short silicone tube extending from the case and discretely traveling down the front fold of the ear and into your custom ear mold which sits comfortably within your ear. The sound from the hearing instrument is then routed acoustically through this tube and delivered to and through the ear mold.

Recommended for the broadest range of hearing loss, BTE’s typically provide improved hearing and improved communicative capabilities.

Battery size is generally larger resulting in longer battery life. These hearing instruments often yield a sustained period of reasonably stable performance with a useful life expectancy of 5-7 years assuming no significant change in hearing acuity or hearing instrument abuse.

Benefits:

  • Easy to operate and manipulate

  • Good durability and longevity

  • Broadest hearing loss application and best range of pricing

  • Most trouble free, least expensive to service and maintain

There is a thin tube (or narrow tube) variation of the BTE, which is fit more typically only for specific types of hearing loss (typically extreme high frequency losses). As such, they are not recommended for everyone. Often such hearing instruments are merely masquerading as the more highly desired and effective RITE (Receiver-in-the-ear) styles.

Receiver-in-canal (RIC) or Receiver-in-the-ear (RITE)

(Receiver-in-the-Ear), also referred to as RIC (Receiver-in-the-Canal) – Initially seemingly similar to BTE hearing instruments in that there are choices of sleek highly ergonomic stylized cases of various colors and sizes that sit securely and unobtrusively above and behind the ear.

However, it is there that the similarities to BTE’s end. This newest state-of-the-art technological hearing instrument uses a cosmetically miniature, discreet wired receiver which attaches at the case and travels down and sits comfortably within the ear canal. There the micro receiver is protected with a soft comfortable open-fit flexible silicone dome or a miniature inconspicuous customized earmold. This means that the in-the-canal micro receiver is more efficiently amplifying directly within your ear canal, as opposed to having to be further away within the case.

This newest technological advancement allows for a more practical open fit in-the-ear-canal receiver which provides the wearer with superior clarity through delicate, discrete amplification.

The “open ear fitting” also provides for the natural “inclusion of sound” by including the desired natural sounds and speech that exist in your world. This inclusive technology results in a more brilliant reproduction of sounds that you have lost, and seek to regain as you remember them. Earlier hearing instruments all “exclude” the natural sounds and speech you want to hear by limiting you to only the sounds that come through its amplifier.

These are currently the most popular instruments for both patient and hearing professional alike. Their smaller ergonomic styles, shapes, sizes and technological capabilities make them typically the easiest and most effective hearing instrument products to fit, operate and maintain. As a result the wearer quickly experiences this revitalized real world sound connectivity, and can expect more trouble free use and longevity.

Battery size is sufficiently large resulting in longer battery life. These hearing instruments often yield a sustained period of reasonably stable performance with a useful life expectancy of 5-7 years assuming no significant change in hearing acuity, hearing instrument abuse, or continued technological advancements.

Recommended for the broadest range of hearing loss and typically provides the most beneficial improved hearing and communicative capabilities for the greatest longevity.

  • Benefits:

  • Reduced feedback

  • Better integrated and less distorted, softer amplification delivered more directly to the eardrum

  • More acceptable, cosmetically suitable and more discrete than traditional BTEs

  • Smaller cosmetically discreet miniature colorized sizes

  • Best technological digital application across a broader range of hearing loss
