Audiology: Hearing Aids

Hearing aids are miniature electronic devices that sit in or on the ear. A microphone collects environmental sounds and speech, amplifies the sound based on the individual’s hearing loss, and delivers it back to the ear. Hearing aids are available in a variety of styles to fit people’s cosmetic needs and power requirements.

Hearing Aid Styles

Today hearing aids are smaller, more comfortable and more effective than ever before. Advances in hearing aid technology continually provide new ways of connecting with the world. Satisfaction rates among hearing aid users continue to improve because of these factors. Even basic models today provide more features than the most advanced models available a few years ago. The following is a description of the most commonly fit hearing aid styles:  

In-the-Ear Styles

Hearing aids worn in the ear are custom-fit, meaning a mold of the ear is made and the hearing aid is built to fit the patient. These are available in different skin tones to camouflage with the outer ear. There are several sizes of in-the-ear hearing aids. Each styel is listed below, ranging from smallest to largest. The size of hearing aid recommended to an individual is based on power needs, cosmetic considerations, dexterity, access to wireless technology and different processing features.

Completely-in-the-Canal (CIC)

The smallest custom style, CIC instruments fit deeply and entirely within the ear canal. CIC instruments are designed to fit mild to moderate hearing losses. They offer high cosmetic appeal as CICs nearly invisible when worn. Even some of the smallest CIC instruments can now wirelessly connect to remote controls for volume and program changes if needed.

In-the-Canal (ITC)

ITC instruments sit in the lower portion of the outer ear bowl, making them comfortable and easy to use. ITC instruments are slightly larger than CIC instruments. ITCs have a longer battery life than CICs and can host additional features such as directional microphones for better understanding in noisy environments, as well as volume and/or program controls. ITC instruments are designed to fit mild to moderate hearing losses.

Half Shell (HS)

Half shell models fill half the bowl of the outer ear. Like ITC models, their size enables the addition of features such as directional microphones, volume controls and push buttons to activate special settings for different listening environments. Because of their size, they may be easier than smaller models to handle for some people and yet are still often disguised by hairstyles.

Full Shell or In-the-Ear (ITE)

Full shell models fill the outer ear bowl. Their size allows the maximum number of additional controls and features such as directional microphones. They use a larger battery size and are more easily manipulated for individual’s with dexterity concerns. ITE instruments size allow for a larger receiver with enough power designed to fit up to severe hearing losses.

Behind-the-Ear Styles

Behind-the-Ear (BTE) models sit behind or on top of the outer ear, with tubing that routes sounds down into the ear. A custom earmold or non-custom ear tip is used to secure the tube in the ear canal. BTEs come in a variety of colors to blend with hair or skin tones or stand out with stylish patterns. Different BTE sizes accommodate different features, controls, battery types and degrees of power.

Mini BTE with slim tube and tip

Mini BTE models house the microphones, internal circuits and speaker of the hearing aid behind the ear in a very small case. Often times these hearing aids are very water and dust resistant. A slim tube connects the case to the ear tip and sound is delivered from the speaker of the hearing aid through the tube to the ear. Mini BTE instruments are designed to fit mild to severe hearing losses.

Receiver in canal (RIC)

RIC models are mini BTEs that have the speaker of the instrument incorporated in the ear tip, instead of in the main body of the instrument. RIC instruments fit mild to severe hearing losses. This hearing aid style looks similar to the Mini BTE when worn on the ear.

BTE with earmold

BTEs with earmolds fit mild through profound hearing losses. They are larger and fit the contour of the ear. The earmold is custom made by taking an impression of an individual’s ear. The sound from the hearing aid is routed into the ear through the tubing of the earmold.

Hearing Aid Accessories & Wireless Technology

While hearing aids offer an improvement in speech understanding for those with hearing loss, there are some environments where individuals continue to struggle to understand conversations. Therefore, many hearing aid companies have developed accessories to assist the individual with hearing loss and maximize their benefit from the hearing aids. The following are some commonly used accessories:

Hearing aid accessories  

REMOTE CONTROL

A remote control gives the hearing aid user the ability to turn the volume of the hearing aids up and down. It also typically allows access to specially designed programs for difficult listening environments. For example, some individuals will have a program specifically tuned for use in the car, or a restaurant.

PHONE ACCESSORIES

A phone accessory typically connects to a hearing aid user’s cellphone via Bluetooth technology. The user is then able to hear their phone calls streamed directly through their hearing aids hands free and without the need to bring the phone to the ear.

EXTRA MICROPHONE

Extra microphones wirelessly communicate with the individual’s hearing aids. This allows the hearing aid user to clip the microphone near or on the sound source of interest. What is picked up by the microphone is streamed directly into the hearing aids, decreasing the negative effects of distance and background noise. For example, the microphone can be clipped to the shirt of a companion at a restaurant or in a car, or it can be placed on the podium at a meeting or presentation.

APPS

Many hearing aid manufacturers utilize Apps on cellphones to control the settings of the hearing aid. This allows the individual to use their cell phone as a remote control and sometimes a streaming device without the necessity of purchasing an additional device.  


Hearing Aid Services

The Audiologists are able to evaluate and repair any make or model of hearing aid. Hearing aids can be tested with state of the art equipment to provide objective information about how the hearing aid is working, regardless of where the hearing aid was purchased. If you are experiencing difficulties with your hearing aid, stop in or call for an appointment today.

All sizes and styles of digital hearing aids are available at Trinity Health. The clinic offers hearing aids from each of the major hearing aid companies: GN Resound, Phonak, Oticon, Signia, Starkey and Widex. We understand every patient experiences unique environments and listening needs. Therefore, we offer a wide variety of options to fit every lifestyle and budget. The Audiologists work together with the patient to select the best quality hearing aid for their level of hearing loss and their particular lifestyle requirements during the communication needs assessment.

Hearing aids can be expensive and may be difficult to afford. Prior to the communication needs assessment, our audiology assistants will verify hearing aid benefits offered through your health insurance policy. If you do have insurance coverage for hearing aids, you will be aware of any out-of-pocket expenses prior to the hearing aid fitting. We work with CareCredit for financing options, in addition to community organizations for financial support as needed.


If a hearing evaluation together with the Ears, Nose and Throat determine there are no further medical options to treat hearing loss, a communication needs assessment will be recommended. Please see the communication needs assessment page for more information.

The FDA recommends hearing evaluation be completed within the past six months before obtaining hearing aids. If you are interested in pursuing hearing aids or learning more about hearing aids, we recommend you schedule a hearing evaluation and communication needs assessment with our audiologists by calling (701) 857 -5986. If you already had a hearing evaluation, feel free to schedule a communication needs assessment and be sure to bring your results with you so the audiologists can provide the most accurate recommendations. Please bring a spouse, family member or friend to the communication needs assessment and the first hearing aid fitting appointment.
