How to protect hearing?The World Health Organization released the world hearing report, a terrible data: it is estimated that more than 900 million people will have hearing loss by 2050. Once hearing loss occurs, most of it is irreversible, and our life will be in trouble. While paying attention to protecting our eyesight, we must not ignore the protection of our ears and hearing.
What is the best way to protect hearing ？
Generally, the voice of normal people is about 40-60 decibels, and the voice in class is about 70 decibels, but the volume when listening to headphones often goes to more than 85 decibels (more than 85 decibels will damage the ciliated cells of the cochlea)
1.Reduce exposure
the use of headphones on commonly used output devices for 3 hours can cause a temporary hearing threshold shift of more than 10dB; Therefore, not wearing headphones for a long time is an important measure to isolate noise damage. Often wear headphones, especially those who like to wear built-in headphones to listen to CDs, should master the principle of 60 ~ 60 ~ 60, that is, when listening to music, the volume should not exceed 60% of the maximum volume, the continuous listening time should not exceed 60 minutes, and the external sound should not exceed 60 dB. Fans who wear built-in headphones to listen to MP3 should follow the principle of 80 ~ 90, that is, the volume should not exceed 80% of the maximum volume and the continuous listening time should not exceed 90 minutes.
2. Reduce negative emotions
The study found that anger, depression, sadness and other negative emotions may induce sudden deafness.
Clinically, it is found that young patients with tinnitus and deafness usually have a period of excessive fatigue before they get sick. For example, many white-collar workers reported that they worked overtime continuously before deafness, slept less and felt very tired; Student patients mostly said they had the experience of staying up late before the exam.
3.Personal protection
for those who participate in noise activities, use earplugs, earmuffs and sound helmets when necessary. Actors and staff can choose appropriate earplugs for protection according to their working environment. Those who like sound entertainment also try to wear earplugs when participating in large-scale entertainment activities such as concerts.
4.Healthy diet
If we eat these high calorie foods for a long time, the blood flow in our body will be blocked, which will easily lead to some lesions in our inner ear tissue, and then there will be different degrees of hearing loss, tinnitus and other problems in our ears. Therefore, we should pay attention to diet and reasonable diet is the basis of ensuring health.
5.Good habits
developing good ear habits is very important to protect hearing. How to use the ear correctly includes:
(1) Don’t dig your ears often;
(2) Keep the ear canal dry;
(3) Blow your nose correctly;
(4) Ear diseases should be treated in time.
(5) It’s best not to listen to music with headphones in noisy places such as buses or streets, because people often unconsciously increase the volume in order to cover the noise, which will do more harm to their ears.
(6) If you don’t listen to headphones when you sleep, the earplugs are sandwiched between the pillow and your ears, which will cause damage to the eardrum; If you fall asleep listening to music, the damage will be more obvious when your ears are dormant.
(7) Improve self-protection awareness at all times, and conduct hearing examination for high-risk groups regularly.
The hearing impairment of the elderly will have varying degrees of impact on the life, safety, psychology and other aspects of the elderly. Therefore, the hearing problems of the elderly can not be ignored. Intervention should be carried out to help the elderly spend their later life better.
From birth, we need to pay attention to the examination of hearing. If there is a problem with hearing, we can achieve early detection, early intervention and early recovery. Everyone wants to listen clearly, so no matter what age we are, we should protect hearing, have good hearing and better listen to the voice of the world.
