A hearing aid is a device that helps people with hearing loss hear sounds. It amplifies sound, allowing the user to better hear what others are or the sounds around them. Hearing aids are most suitable for people with hearing loss between 41 and 80 dB HL.
01.Depending on the type of loss, hearing aids are mainly divided into two types:
- Air conduction hearing aids
• Suitable for most patients with sensorineural deafness or mixed deaf.
• According to the wearing method, they can be divided into behind-the-ear, in-the-ear, etc.
• Among them, the-the-ear canal hearing aid can be hidden in the ear, almost invisible, and suitable for people with high appearance requirements. - Bone conduction hearing devices
Suitable for patients with conductive deafness, atresia of the external auditory canal, or sequelae of otitis media.
• It does not transmit sound the ear, but directly stimulates the inner ear through bone vibration, helping to hear sound.


If the hearing loss is very serious (>80 dB HL) or deaf, a cochlear implant may be a better choice. But if surgery is not possible for the time being, you can also try an extra-powerful hearing aid
02.How to choose a hearing aid scientifically?

- Wearing it in both ears is better than in one ear
• you have hearing problems in both ears, it’s best to wear a hearing aid on both sides.
• This can better distinguish the direction of sound, hear more, and not get tired easily.
• But if one ear has very poor hearing or very low language discrimination, you can only wear it on the better side. - Choose according to your needs
• Elderly people: suitable for behind-the-ear hearing aids, which are easy to operate, loud enough, and also prevent falls and moisture.
• Young people or those who care about appearance: you can choose in-the-ear hearing aids, which are hidden in the ear almost invisible.
• Children or patients with special diseases: need to adjust the hearing aid regularly to ensure that it does not affect language development. - attention to the functions of the hearing aid
• Today’s hearing aids have many intelligent technologies, such as noise reduction, Bluetooth connection, and automatic volume adjustment. • For example, wide dynamic compression technology can automatically adjust the volume of sound, making it more comfortable for the user to hear in a noisy environment
03.How to adapt to hearing aids? How to maintain them?

- Adapt gradually
• Start in a quiet environment: When first start wearing them, use them at home or in quiet places, and then gradually move to noisier places.
• Increase wearing time gradually: Wear them for -2 hours on the first day, and then gradually increase the time until you can wear them all day (take them off when sleeping).
• Practice communication: Spe to one person face-to-face at first, and then try group conversations after getting used to it. You can also listen to the news or read aloud to improve your language. - Daily maintenance
• Prevent moisture and falls: Store them in a dry box when not in use, and avoid getting them wet or sweating on them Be careful when handling them to avoid dropping them.
• Regular cleaning: Use a small brush to clean the microphone hole and earwax, and do not use chemical cleaners
• Battery management: Take out the battery when not in use for a long time, and avoid exposing them to high temperatures. - Regular review
• After wearing a hearing aid, have a hearing test every six months to a year to have the audiologist adjust the parameters ensure the effectiveness of the hearing aid.
Summary
Hearing aids are important tools to help people with hearing loss return to the sound world, but they must be scientifically selected and used correctly. understanding the types of hearing aids, the applicable population, the selection methods, the adaptation process and maintenance skills, people with hearing loss and their families can better use them. Our goal “healthy listening, barrier-free communication”, to let technology help people with hearing loss better integrate into society, enjoy a rich life, and believe that with the joint efforts of international community, the cause of hearing health will be better and better, bringing more hope and happiness to people with hearing loss.
