       March 3 this year is the thirteenth National Ears Day. The theme is “Reduce Noise, Protect Hearing”. Who are the common people with noise-induced deafness? What are the manifestations of noise-induced deafness? How to prevent and treat noise-induced deafness?

Who are the common people with noise-induced deafness?

Noise-induced deafness is common in people working in high-noise environments, such as telephone operators and wireless workers who often wear headsets, riveters, blacksmiths, textile workers, naval engineers, tank pilots, aircraft field crews, dance halls and KTV workers.者 etc.

What are the manifestations of noise-induced deafness?

The main symptoms are progressive hearing loss and tinnitus, which have no obvious effect on ordinary speech. It was only found in audiometer examinations. Later hearing damage gradually developed to high and low frequencies, and finally decreased generally. At this time, hearing impairment is felt. In severe cases, it can be completely deaf. .Tinnitus and deafness can occur at the same time or separately. It is often high-pitched tinnitus, which is disturbing day and night.

In addition to hearing damage, noise can also cause headaches, dizziness, insomnia, high blood pressure, changes in electrocardiogram, and can also affect gastric peristalsis and secretion.

How to prevent noise-induced deafness?

预防噪声性耳聋应注意以下几点:1.控制噪声来源,改善劳动条件:这是最积极最根本的办法。2.减少接触时间:在隔音室里休息,或减少每日、每周的接触噪声时间,也可降低发病率。3.广大青少年平时使用MP3、MP4音量尽可能低些。一般不宜超过80~90分贝,连续收听时间不宜超过1小时。4.耳部隔音,戴用耳塞、耳罩、隔音帽等防声器材,简便者可用棉花塞紧外耳道口,再涂抹凡士林,其隔音值可达30dB。5.卫生监护,就业前应检查听力,患有感音神经性耳聋和噪声敏感者,应避免在强噪声环境工作,对接触噪声者,应定期检查听力,及时发现早期的听力损伤,并妥善处理。

How to treat noise-induced deafness?

There is still no real effective therapy, but early detection and early intervention are needed; treatments include cochlear vasodilators, ATP, vitamins, etc.Can be worn by patients with moderate deafness Hearing aid , Patients with severe deafness can undergo cochlear implant surgery.

What is a cochlear implant?

Cochlear implant, also known as electronic cochlea, is an electronic device that replaces the functions of the human ear. It can help adults and children suffering from severe and severe deafness recover or provide a sense of hearing.

Severe and severe deafness patients here refer to those whose binaural hearing threshold is greater than 75 decibels (dBHL) or above, and who wear high-power hearing aids are ineffective.Cochlear implant technology began in the 50s. After decades of development, especially with the emergence of high-tech such as biomedical engineering, it has moved from experimental research to clinical application and has become the only effective treatment for hearing loss in patients with total deafness. method.According to statistics, more than 5 deaf patients worldwide have used cochlear implants.

Which patients are suitable for cochlear implants?

For patients with pre-lingual deafness, in addition to regaining their sense of hearing, they must also learn language.Generally, the optimal age for implantation is under 8 years old, because 5 to 8 years old is the best time to learn language, and it is relatively difficult to learn language after 8 years old.Post-linguistic deaf patients do not need language training, and there is no age limit.

Of course, in addition to age factors, the patient should not have serious external ear and middle ear diseases and systemic serious diseases, and should also have a stable psychology, have a correct understanding of the effects of surgery, and be able to adhere to language and hearing training for a long time.
