How to isolate our ears from noise? Our ears are very fragile. Noise is one of the four major public hazards in the world. Noise can damage the sensory hair cells of the auditory organ (cochlea) of the ear. I feel that once the hair cells are damaged, they can never recover. Let's take a look at how to isolate the ears from noise.
How to isolate ears from noise 1 Modern people have paid a serious health price for noise. Living in a noisy environment for a long time will not only cause noise deafness, but also produce neurasthenia symptoms such as headache, insomnia and tinnitus.
Affect the development of the nervous system, it is difficult to concentrate, and it is irritable. Therefore, the harm of noise to people is not limited to being unable to sleep, and it is extremely unwise to pay no attention to noise.
Robert koch, a great German medical scientist, once said, "One day, mankind will continue to fight against noise, just like cholera and pests." Noise is not only a sleep killer, but also a mental killer. For the sake of our health, we should start fighting noise now and learn to solve the big problem of noise!
For the effect of noise reduction, two pieces of cotton are decorations. Ordinary anti-noise earplugs are either completely ineffective or can't be completely isolated, which can't give consideration to noise reduction and stress. Recommend the best noise-proof earplugs. Non-zero sound-proof earplugs will definitely subvert your stereotype of earplugs.
Zero-hearing sound-proof earplugs have been focusing on China's ear canal for more than ten years, and have successively passed EU CE certification, ISO900 1 quality certification, China People's Liberation Army and CMA medical acoustic testing, CDC health monitoring, and have strong authoritative endorsement strength.
Zero-listening noise-reducing earplugs are made of patented slow-rebound sponge material containing Z 15 sound-absorbing particles, which has excellent antibacterial design, sound insulation effect and comfort, porous characteristics and good air permeability, and is suitable for long-term sleep.
Sanitary and portable, and can be used for a long time. After mild cleaning, it can be reused for three to six months, and the cost performance is quite good.
The core noise reduction values of zero-listening earplugs are as high as 44 and 5dB, which are 10dB higher than similar products. Whether sensitive to sound or immune to noise sources, zero-noise earplugs can help us shield all noise sources.
In modern city life, noise is overwhelming. The fast-paced way makes us suffer from big or small urban diseases, and a large part of the reason comes from the noisy living environment-noise. But it doesn't matter, put on zero-listening sound-proof earplugs and embrace a comfortable and quiet living environment from now on!
How to isolate ears from noise II. How to effectively reduce the noise in the ear?
Reduce noise at the sound source ―― For noisy things like motorcycles and cutting machines, install mufflers on motorcycles and put sound-proof sponges next to large machines.
You can put up a sign against whistling next to the school.
Stay away from noise or set up barriers-noise barriers can be installed around houses along the expressway, and a large number of trees can be planted next to them.
The glass in the school classroom is double-decked.
Isolate noise from the human ear ―― just like a shooter wearing special earplugs.
Noise isolation method
1, noise propagation can be effectively reduced by reducing noise, controlling noise propagation and changing the noise propagation path that has been emitted by the sound source, such as taking measures such as sound absorption, sound insulation, sound barrier and vibration isolation.
2. When the noise protection of the receiver or receiver fails to take measures in terms of sound source and transmission route, or acoustic measures still fail to achieve the expected effect, it is necessary to take protective measures for the receiver or receiver, and ear protectors can be used.
Ear protectors are personal protective articles that protect people's hearing from strong noise. Common ear protectors include sound-proof earplugs, earmuffs or helmets. For example, workers exposed to occupational noise for a long time can wear ear protectors to isolate noise.
How to isolate ears from noise 3. The damage of noise to ears
Many studies show that noise is another invisible killer of hearing loss.
The effect of noise on people's hearing loss is like boiling a frog in warm water. It will get more and more serious as time goes on, and it may come quietly without you realizing it. For example, if your hearing is normal, going to a noisy concert may cause tinnitus or make your ears feel stuffy, and these problems may disappear in a day or so.
However, repeatedly exposing yourself to unsafe sound levels for too long will eventually damage hair cells in the ear irreversibly. Keeping away from noise sources, reducing the volume of noise sources, limiting exposure time and wearing hearing protection equipment (such as noise-proof earmuffs) are effective measures to prevent noise-induced hearing loss.
It is especially recommended that workers working in noisy environment wear effective anti-noise earplugs in time to avoid waiting for a long time in noisy places and let their ears have a full rest.
How to avoid noise damage to ears?
1, do a good job of daily noise protection.
Wearing high-quality earplugs, earmuffs or sound-proof caps helps to protect hearing.
2. Avoid working in a noisy environment.
Not only musicians or machine tool operators, but also any noisy working environment such as machines and large vehicles. If you work in this environment, it is recommended that you have regular hearing tests, and pay attention to noise prevention at work to avoid strong sound stimulation.
3. Wear noise-canceling headphones.
Many workers put on music equipment to drown out the background noise. Wear noise-reducing earplugs instead of turning the volume of your favorite music to a dangerous level. This can not only reduce the overall noise pollution, but also bring no extra pressure to the ears.
4. Don't dig your own ears.
Usually, it is not recommended that you dig your ears with a stick-like tool such as a cotton swab. These tools will not only puncture your periosteum and damage your hearing, but also inadvertently push wax and debris further into your ear canal, resulting in uncomfortable accumulation.
5. Use noise protection equipment such as earplugs when necessary.
If you have hearing loss or risk of hearing loss, you should use noise protection equipment such as earplugs in the workplace, streets and any other noisy places.
