How to choose a suitable hearing aid

Hearing loss can occur at any age. Its effects are far more than just inaudible voices. What’s more terrifying is that it can lead to social and mental decline, and the elderly are more prone to Alzheimer’s. Hearing aids can restore part of your hearing and allow you to return to normal life, but there are quite a variety of hearing aids on the market, and it is very difficult to find a suitable one. Hope this article can help you!

How do hearing aids work?

Hearing aids improve hearing by amplifying external sounds. It usually consists of the following parts:

Microphone: Receives sound from the environment. Good hearing aids have two microphones, one omnidirectional and one directional.

Amplifier: Enhances the sound.

Receiver: Actually a speaker that delivers amplified sound to your ears.

Processor: Contains custom programs and data to optimize the sound heard. Generally better hearing aids have two processors.

Battery: Power supply for hearing aids, most of which are currently charged.

Olders usually amplify all the surrounding sound, so there will be a lot of noise. Hearing aids on the market today generally convert sound into digital signals for more advanced processing. Not only can digital hearing aids be customized for hearing problems, they can also filter out loud background noise and selectively amplify desired sounds, such as speech or music. Plus: Artificial intelligence enables state-of-the-art hearing aids to automatically adapt to their surroundings, and also supports some manual settings.

What type of hearing aids are there?
Hearing aids come in many different shapes and sizes.

The most suitable option depends on the severity of the hearing loss, but also personal preference. If there is only mild hearing loss, a model that does not block the ears should be better. And if you wear glasses, you may want to avoid hanging hearing aids behind your ears. It's important to note that smaller hearing aids generally require more routine maintenance.

Below is an overview of the most common types of hearing aids and their pros and cons.

In-canal (CIC)

In-the-canal (CIC) or invisible (IIC) hearing aids are the smallest hearing aids on the market. They are placed deep in the ear canal and are almost invisible from the outside. There is only a small plastic handle that allows you to place the hearing aid.

Due to its small size, the battery life is limited and the included features are limited. This makes them best suited for people with mild to moderate hearing loss.

Semi-in-the-canal (ITC)

Semi-in-the-canal (ITC) hearing aids are slightly larger than full-in-the-canal models. Because they provide space for control, you don't have to access the app or remote every time you need to adjust the volume or program. But no vents are shaped to block the ears, which means the user's own voice or chewing may sound louder.

In-the-ear (ITE)

In-the-ear (ITE) is also a custom hearing aid that fills the entire external auditory canal or ear. They have better processing and amplification than smaller models, so it's a good option for those with more severe hearing loss. They are more suitable for people with less convenient life.


The on-ear (BTE) model is much larger than a hearing aid that sits directly in the ear, but it is less visible on the front than the larger ITE or ITC types. A clear plastic tube directs the amplified sound into the ear, usually connected to a custom-made ear tip in the ear canal.

As its size allows it to carry more cells and components, the processing and amplification offered by the BTE model is the most advanced of any type. This also makes this type best for people with moderate to severe hearing loss, although BTE style hearing aids are also a good choice for people with mild to moderate hearing loss.

In-ear receiver (RIC)

In-ear receiver hearing aids are similar to BTEs, except for the positioning of the receiver. It can make the model smaller and still guarantee power or function. This is the best option for those who can't hear high-pitched sounds.

When you choose RIC hearing aids, you must also have disposable ear tips or domes. The soft silicone tip covers the receiver, securing it in the ear canal and protecting it from earwax. You can choose from closed domes, open domes, and more, each available in a variety of sizes. If a person with mild to moderate hearing loss can still hear external sounds, an open dome should be selected. A professional doctor can help you find the perfect type for your ear.


Earbuds are a combination of true wireless earphones and hearing aids. Strictly speaking, it's not really a hearing aid, because you can't make fine adjustments to hearing like hearing aids, and they use a different technical route. However, in-ear hearing aids are more suitable for young people with mild to moderate hearing loss.
