Application skills of hearing aids

With the improvement of people’s life quality, more and more deaf people choose hearing aids to improve communication. But why do some people’s hearing aids last for years, while others often “sound the alarm” – either return to the factory for maintenance, or the sound is not as clear as it was at the beginning?

The common failures of hearing aids are silence, noise, low noise and noise. The causes of silence include insufficient power or voltage of hearing aid, damp, blockage and rupture of ear hook damping, blockage of cerumen baffle, rupture and fall off of ear mold and acoustic pipe, blockage of microphone, dirty or blocked dust screen of microphone, deformation and rust of electrode contacting battery. The causes of noise are dirty dust screen of microphone, improper matching parameters (very low noise or excessive low-frequency amplification). The reasons for the low sound of hearing aids include foreign matters in the ear canal or hearing loss; insufficient battery power or voltage; rupture or blockage of ear mold and acoustic pipe; dirty or blocked microphone dust screen; failure of auxiliary parts of hearing aids; low gain or output.

The receiver of the hearing aid is the core part of the hearing aid, and the replacement and maintenance prices are expensive (except within the warranty period), so the correct maintenance is very important for users, and the most immediate approach. Especially for the users of the earphone, they should take good care of the receiver. The three maintenance points of the inner ear machine are to prevent cerumen, dampproof and falling of the machine.

Point one: cerumen prevention

Dr. Yang Xinyi pointed out that users should first clean the ear canal before wearing hearing aids. If there is a small amount of cerumen or there is cerumen near the ear canal mouth, they can clean it by themselves; if there is more cerumen or the location is deeper, they must go to the hearing center and ask experts to take it out. In addition, the user should clean the sound outlet of the receiver (cerumen prevention device) every day and keep the reliability of cerumen prevention device. The device can effectively prevent cerumen from entering and prolong the service life of the receiver.

Experts suggest that cerumen baffle is the most important protective device of customized machine. Nowadays, the traditional white net cover, hat net cover and cerumen baffle with extended acoustic tube can not meet the needs of all users. Users can choose a new generation of cerumen baffle according to their own needs. Among them, the cerumen baffle with the press type elastic head can quickly clean the cerumen blocked in the hole, and can be reused, which is suitable for the users of dry cerumen. The diameter of the base of the new cerumen baffle which can prevent oil cerumen is more than 3.8mm, which has a great demand on the ear canal. Moreover, users should pay attention to the fact that its net cover will reduce the 3dB gain of the hearing aid. It is not suitable for users to select the ultimate power. The Hf4 net cover is characterized by fine mesh, and the cerumen is not easy to fall into the receiver when replacing, so it is suitable for users of large dry cerumen.

Point 2: moisture proof

Yang Xinyi pointed out that before swimming, bathing, shampooing and face washing, take out the inner ear hearing aid and clean the ear canal with cotton stick; before contacting or adjusting the hearing aid, wipe the water on your hand; try to avoid wearing the hearing aid outdoors in rainy days or in high humidity environment, once used in these environments, use electronic or common desiccant as soon as possible to dry it thoroughly.

Point 3: prevent falling

Experts pointed out that the inner ear machine is usually small in size, its internal structure is very precise, and the thickness of the shell is less than 0.8mm, which may cause sound distortion or decrease after being impacted or dropped, and it is very easy to cause shell fragmentation after falling to the hard ground. In order to prevent the hearing aid from falling during wearing, it is recommended that children and the elderly choose the ring cable. In addition, when taking and wearing the hearing aid, you should hold the hearing aid with your thumb and index finger, and pull out the hearing aid while rotating. Do not pull the battery door and program button to avoid breaking the battery door and falling off the button.

Experts pointed out that “the person who has the longest contact time with hearing aids every day is the user himself. Correct use and maintenance are very important, although they are all small skills, but many users just ignore these aspects, which makes the use effect and life of hearing aids affected.”. Therefore, it is called to strengthen the user training of hearing aids, without correct maintenance methods, hearing aids will really sound the alarm “.
