Hearing damage caused by exposure to noise at work is a common occupational hazard. In most cases, noise does not cause damage to human hearing immediately, so it is easy to be ignored, but long-term exposure to excessive noise can cause hearing loss.
Labor protection noise-canceling earplugs are generally made of silicone or low-pressure foam material and highly elastic polyester material. After being inserted into the ear canal, it comes into close contact with the external ear canal to isolate sound from entering the middle and inner ears (eardrums), to achieve the purpose of sound insulation, thereby protecting the hearing of workers. Labor protection noise-canceling earplugs can prevent eardrum discomfort caused by the sound produced by the machine. The anti-noise performance is good, but it is hard, and it has obvious pain and pain when worn, which is not suitable for sleep. Generally, the labor protection earplugs are provided with a rope, which is convenient for removal at any time.
China hand tools supplier believes that "to prevent hearing loss, we must first consider adopting engineering control measures and management measures, such as adding sound barriers, isolating or controlling sound sources. If proactive preventive measures cannot completely eliminate the noise hazard, earplugs are needed at this time.
To play the role of earplugs, you must use and maintain them properly. Before wearing the earbuds, wash your hands and use clean earbuds.
Instructions:
Scrub: Roll the earbuds into strips. The thinner the ear, the easier it is to wear. Insertion: Pull up the upper ear corner and insert two-thirds of the earplug into the ear canal.
Hold: Hold the earbuds for about 20 seconds until the earbuds swell and block the ear canal. Pull out: When removing the earbuds after use, gently pull the earbuds out.
Ear Plug
China Hand tools manufacturer teaches you the quality of earbuds:
1. The slow rebound effect, elasticity is too large, anti-noise earplugs compress the skin of the external ear canal, which can cause discomfort such as ear distension, ear pain, etc .; Therefore, you must observe the rebound speed of the earbuds. The longer the rebound time, the better the quality.
2. Softness, softness directly affects the comfort of wearing earplugs.
3. Surface texture, some earplugs feel sticky, and they can stick to the skin of the ear canal when worn and should be avoided as much as possible. The best way to identify them is to stick the two earplugs tightly together and then separate them. The faster they are, the better, except for wax pills and silicone earplugs.
The basis for checking whether the earbuds are worn well:
After wearing the earbuds on both sides, you can perform a simple test to determine whether the earbuds are properly worn by covering your ears tightly with both hands and then releasing them to distinguish the amount of noise heard. If the earbuds are worn well, you should hear the same amount of sound when you cover them with your hands and when you don't cover your ears. If you feel that the sound you hear when covering your ears is significantly smaller than when you do n’t cover it, it means that the earbuds are not worn properly. At this time, you need to re-wear the earbuds and check the wearing position according to the method described above.
Finally, it is very important to properly maintain the noise reduction earbuds, which can keep the earbuds in a good condition, maintain a good noise reduction effect, and also help extend the life of the earbuds.
