Selection and use of hearing aid tips

Hearing Aid Features

In simple terms, hearing aids expand the sound and make it easier for deaf people to hear. The selection of hearing aids is an important part of hearing rehabilitation. Proper use of hearing aids can help deaf people effectively use residual hearing and rebuild their communication skills.

The hearing aid is composed of a microphone, a loudspeaker and a speaker (commonly known as a horn). In addition, some hearing aids must be used with ear molds. In addition to fixing the hearing aid, preventing sound input and making it comfortable to wear, the ear mold is more important for improving the acoustic characteristics of the hearing aid, affecting its sound output, and making it more suitable for wearers.

Hearing aid accessories include batteries, moisture-proof beads, dehumidifiers, etc.

What you need to know about hearing aids

Just like buying eyeglasses, you should go to a center with a professional audiologist when you buy hearing aids. In general, before fitting a hearing aid, the person concerned should conduct a comprehensive hearing test for the deaf to determine the extent and type of hearing loss of the deaf. Each hearing aid type has its own adaptation range, such as a wide range of hearing loss corresponding to a BTE hearing aid, which is more suitable for severe or deep hearing loss.

In addition, when choosing a hearing aid, the deaf can consider their own preferences and physical factors. For example, the degree of finger flexibility and vision can affect whether a deaf person is suitable to use a compact hearing aid, otherwise it will be difficult to install a battery and adjust the volume or reception mode.

After the hearing-impaired person has selected a hearing aid, the shape of the external ear canal needs to be inverted to form an ear mold or a hearing aid casing. When making ear molds or cases, the hearing center staff should adjust the hearing aid according to the hearing of the deaf to meet the needs of the deaf. Due to the different living habits of each deaf person, he should go to the hearing center for follow-up adjustment after a few weeks of initial wearing of the hearing aid.

Hearing Aid Tips

Hearing aids should not collide to avoid disconnection of the sound tube and damage to internal parts.

Avoid moisture, water and overheating. Hearing aids are not allowed for swimming, bathing, etc. You should also take off your face when washing your face, and pay attention to protection when it rains.

The lack of power will affect the effectiveness of the hearing aid, so pay attention to replacing with a new battery.

Digital hearing aid programs should not be adjusted without authorization.

Hearing aids should not be disassembled without authorization.

Always keep your ear canals clean and avoid hearing aids when your ears become inflamed or feel unwell.

Use a brush and a clean, dry cloth to remove dirt from the hearing aids before wearing it every day.
