1. Behind-the-ear (BTE) hearing aids: These hearing aids are worn behind the ear and have a small plastic case that houses the electronic components. They are connected to an earpiece or earmold that fits inside the ear canal.
2. In-the-ear (ITE) hearing aids: These hearing aids are custom-made to fit inside the outer ear. They fill the bowl-shaped area of the ear and are less visible than BTE hearing aids.
3. In-the-canal (ITC) hearing aids: These hearing aids are custom-made to fit partially in the ear canal. They are less visible than ITE hearing aids but may not be suitable for individuals with severe hearing loss.
4. Completely-in-the-canal (CIC) hearing aids: These hearing aids are custom-made to fit completely inside the ear canal. They are the smallest and least visible type of hearing aid.
5. Invisible-in-the-canal (IIC) hearing aids: These hearing aids are custom-made to fit deep inside the ear canal, making them virtually invisible when worn. They are suitable for individuals with mild to moderate hearing loss.
6. Receiver-in-canal (RIC) hearing aids: These hearing aids have a small case behind the ear that houses the electronic components, while the receiver (speaker) is placed inside the ear canal. They are connected by a thin wire, making them less visible.
7. Extended wear hearing aids: These hearing aids are inserted deep into the ear canal by a professional and can be worn continuously for several months without removal. They are suitable for individuals with mild to moderate hearing loss.
8. Bone conduction hearing aids: These hearing aids bypass the outer and middle ear and directly stimulate the inner ear through bone conduction. They are suitable for individuals with conductive hearing loss or single-sided deafness.
9. Disposable hearing aids: These hearing aids are pre-programmed and designed for short-term use. They are typically used as a temporary solution or for trial purposes.
10. Assistive listening devices (ALDs): These devices work in conjunction with hearing aids to improve sound quality in specific situations, such as watching TV, talking on the phone, or listening in noisy environments. They include devices like FM systems, loop systems, and Bluetooth streamers.
