a. Bone Conduction Hearing Aid

This type of hearing aid carries the sound vibrations to the inner ear through the bones of the skull with the aid of the skull itself, rather than via the outer and middle ear.

In this sense, it is the most effective for individuals with conductive hearing loss.

b. Air Conduction Hearing Aid

Air conduction type of hearing aids pick up and deliver the sound into the ear canal through the eardrum and middle ear.

They can be adjusted to a wide range of hearing impairments and come in different forms like behind-the-ear (BTE), in-the-ear (ITE), and receiver-in-canal (RIC).

c. Cochlear Hearing Aid

Cochlear implants are small electronic devices that are implanted surgically into your inner ear cochlea.

They circumvent the damaged hair cells in the cochlea and directly stimulate the auditory nerve, bringing the sense of hearing to subjects with severe to profound hearing loss.

d. Over-the-Ear Hearing Aid

These hearing aids are either worn behind the ear or over the ear and a connecting customized ear mold or tubing is used to deliver sound directly in the ear canal.

They can be worn by people with mild to serious hearing loss and are available with different features to fit individual needs and to be customized.

e. Inner Ear Hearing Aid

Inner ear hearing aids, more commonly referred to as ITC or CIC hearing aids, are individually fit devices that are seated inside the ear canal.

They are discreet and deliver natural sound, though they may own lesser functionality due to their small size.

f. Micro Hearing Aid

Micro hearing aids are extremely tiny and plain enough to be indiscernible when worn, unlike other types of hearing aids.

These devices meet the needs of those with either mild hearing loss or moderate hearing loss without any high-end extra features like noise cancellation and directional microphones.

g. Body-Worn Hearing Aid

Body-worn hearing aids feature a tiny device that is either clipped onto the clothing or put into the pocket, while the earpiece can be either connected wirelessly or through a tube/cable.

This type is convenient for individuals with severe-to-profound hearing loss since it has robust amplification features.

h. Digital Hearing Aid

Digital hearing aids combine digital signal processing and sound amplification to enhance the signal.

They feature more advanced stuff like programmability, sound reduction, echo cancellation, and frequency shifting.

i. Over-the-counter (OTC) Hearing Aids

Basically, OTC hearing aids are FDA-approved devices tailor-made for individuals having such hearing problems as light hearing loss or moderate hearing loss.

j. Bluetooth Hearing Aids

Bluetooth hearing aids transfer wireless data to smartphones, tablets, and other Bluetooth-capable devices, and they let users stream audio directly to their hearing aids.

They provide for augmented communication through voice calls, music, as well as media.

k. Invisible Hearing Aids

Invisible hearing aids, like CIC (completely in-canal) and IIC (invisible-in-canal) devices, are custom-fitted to sit in the ear canal so that they are not seen when worn.

They are great for the discreet and natural sound.

l. Waterproof Hearing Aids

Water-proof hearing aids can stand against moisture, so they can be used by those who like to go in for water activities such as swimming or showering.

m. AI Hearing Aids

Human-AI conversation is designed to analyze and adapt to the situation in the hearing environment and process the sound and speech in real-time, in order to optimize the quality of sound and speech understanding in different situations.

n. Custom Hearing Aids

Custom hearing aids are custom-made by professional audiologists for fitting in the specific shape of a patient’s ear canal or a part of the outer ear.

They ensure the highest comfort level, volume, and sound settings as desired by the particular hearing-impaired person.
