During the use of hearing aids and related accessories, the general situation can be checked regularly to ensure normal use in daily life. Users can check the hearing aids through "one look", "two listens" and "three checks", and make targeted solutions according to the corresponding problems.

Take a look. Look for trauma to the hearing aid casing; Look at whether the hook of the hearing aid is cracked or loose; See if the dust cover is clogged; See if the earmold sound hole is blocked; See if the battery is leaking, etc.

Listen to it twice. If there is a sound, it is necessary to distinguish whether the sound is loud, whether there is any change in sound quality, and whether there is whistling. Howling is further divided into internal and external howling. Internal whine is rare and is usually detected during hearing aid repair and is an internal problem of the hearing aid; External whistling is usually caused by a broken ear hook or an ear mold problem, and is more common in daily life. If there is no sound, it may be caused by damage to the inside of the hearing aid and needs to be professionally repaired.

Three checks. Check whether the power is sufficient, usually use a measuring electrometer for testing; To check the performance of hearing aids, this step needs to be consulted

When using hearing aids, keep them away from magnetic environments, such as physiotherapy rooms, CT rooms and MRI diagnosis rooms in hospitals, so as not to affect the use of hearing aids. Also, keep pets such as cats and dogs away from teasing, biting, or swallowing hearing aids.

When not in use for a long time, the hearing aid should be placed separately from the battery to prevent the battery from "leaking" and causing the internal components of the hearing aid to be corroded and rusted.

2. Clean regularly. Hearing aids need to be cleaned regularly, either with a cotton ball or a soft, dry cotton cloth and never with water. Here are the cleaning methods and precautions for different styles of hearing aids.

Behind-the-ear hearing aids, also known as behind-the-ear devices, are hearing aids that are worn behind the ears and transmit sound into the ears through earmolds or earbuds. The biggest hazard factor in the use of behind-the-ear hearing aids is sweat. Due to the corrosive nature of sweat, it is important to clean the skin behind the ears and hearing aids in a timely manner during daily maintenance. Receiver external hearing aids, also known as receiver external behind-the-ear devices, are a popular type of hearing aids in recent years, and their main advantages are small size and good concealment. During the use of the behind-the-ear device, you should pay attention to the removal technique, and do not pull or press the connection line between the receiver and the hearing aid body during the removal and wearing process, so as to avoid the breakage of the receiver connection line caused by external force.

In-ear, in-ear and deep in-ear hearing aids, worn for a long time, are easy to be contaminated by earwax, sweat, bacteria, etc., and can easily lead to ear canal infections if not cleaned in time. Therefore, it is recommended to clean in-the-ear hearing aids three times a week, or once a day if there is a lot of earwax.

3. Regular maintenance. Hearing aids need to be sent to a professional fitting center every six months, where they are maintained by professional engineers and adjusted by professional audiologists to ensure that their hearing aids are in good condition.

⚠ Special attention should be paid to the fact that once the hearing aid fails, it should be sent to a professional maintenance center or manufacturer for repair in time, and it should not be disassembled for repair by itself, so as to avoid damage to the internal components of the hearing aid caused by static electricity and other conditions.

Earmolds. Earmolds are behind-the-ear hearing aid accessories that should also be cleaned regularly. In particular, earwax or dirt must be cleaned when the sound outlet, sound channel, or vent is blocked. Before cleaning, the hearing aid should be separated from the earmold, the ear canal opening should be cleaned with a special cleaning tool, and then the earmold should be cleaned and cooled dry with water or washing liquid to ensure that the sound channel and ventilation hole of the earmold are completely dry and free of water vapor, and then connected to the hearing aid. It is important to note here that you do not use alcohol to clean your earmolds. If the earmold has an aging and hardening of the sound tube, yellowing, cracking, etc., it needs to be replaced immediately.

Battery. The battery is the energy source for hearing aids. Regularly checking whether the battery is fully charged is a necessary operation to ensure the normal operation of the hearing aid. Generally, the normal working value of the battery is 1.4 volts, and if it is lower than 1.1 volts, it will affect the normal operation of hearing aids.

Volume adjuster. The volume adjuster is the volume adjustment button. Adjust the volume gently and avoid pressing too hard or being impacted by external forces. When there is a lot of sweat, it is necessary to dry it in time to keep the outer protrusion dry.

Hearing aid switches. The hearing aid switch, also known as the battery compartment, is one of the most turned on parts of the day and should be turned on and off lightly when in use. Hearing aid switches are often damaged by the user's excessive force, too much force, and improper placement of the battery.

Ear hooks. The ear hook is the front part of a traditional behind-the-ear hearing aid and is tightly connected to the elbow of the earform. In daily use, due to problems such as sweating and cerumen blockage, the earmold needs to be cleaned, and many people will habitually rotate the ear hook to separate the hearing aid from the earmold. However, this operation is wrong, and long-term and frequent wrong operation will cause the root of the ear hook to loosen, break, and even produce sound leakage. The correct way to do this is to separate the earmold connection hose from the hearing aid hook. Although this operation is not as simple as rotating the earhook to separate the hearing aid from the earmold, it can well avoid unnecessary damage to the hearing aid caused by excessive disassembly of the ear hook.

Receiver. The receiver is the most popular part of hearing aids in recent years, and it is very afraid of falling and shock. If it falls vertically at a height of 1.5 meters, it may be damaged, causing the position of the coil in the hearing aid to change, resulting in problems such as reduced sensitivity, distortion, and pitch change of the hearing aid, which will affect the hearing aid effect. Therefore, when taking off the hearing aid, the user should do it on a soft cushion to prevent it from falling.
