Hearing aids are medical devices that amplify sound for individuals with hearing loss. These devices differ in physical design and available features. An audiologist can discuss your hearing needs as well as the options available to you. Here is more information about the different types of devices and how they can help with hearing loss:
Styles and Fit
Hearing aids are available in multiple physical styles that sit on or inside the ear. The type you choose depends on several factors, and an audiologist can discuss the options available to you that fit your unique case.
Behind-the-ear (BTE)
These rest behind the ear and connect to an earmold or dome with tubing. A BTE hearing aid accommodates a wide range of hearing loss levels, and the external placement also makes the device more accessible for handling and maintenance. This style works for adults and children with hearing loss.
In-the-ear (ITE)
ITE hearing aids fit entirely within the outer portion of the ear. Their larger shell compared to the canal styles may allow more space for additional controls and features. Their size can make them easier to handle for people with decreased dexterity. ITE hearing aids are suitable for mild to severe levels of hearing loss.
In-the-canal (ITC)
This style sits partially inside the ear canal, making it smaller and less visible than ITE devices. There are styles that sit even further in the ear canal, completely-in-the-canal (CIC). ITC and CIC styles require smaller batteries; handling the device and replacing the batteries may require greater dexterity and care. Both styles are suitable for those with mild to moderate hearing loss.
Hearing Loss Severity
Hearing loss ranges from mild to profound, with mild hearing loss often requiring less amplification. Not every hearing aid style supports every hearing level, and the device’s capacity must align with the individual’s hearing profile. To select the right hearing aid type, you will likely need a hearing test.
A hearing test is the standard way an audiologist checks for hearing loss and evaluates how well you hear. During the evaluation, the audiologist may use different types of tests to determine whether you have hearing loss and how severe it is. You’ll typically listen for tones, sounds, or words played through headphones in a sound-treated room, and you respond when you hear them. These responses help the audiologist create an audiogram, a chart that shows your hearing ability across pitches and volumes. Based on the results, the audiologist can explain the type and degree of hearing loss you have and recommend next steps, such as hearing devices or further testing.
Use and Professional Care
Hearing aids require routine care to function properly over time. Cleaning removes earwax and debris that interfere with sound pathways. Batteries must be charged or replaced depending on the device type, and maintenance needs vary based on hearing aid style. Hearing care providers can program devices to match measured hearing thresholds, and follow-up visits allow adjustments to sound balance and fit.
