Earmuffs than 3m soundproof earplugs sound effect is good?

"Is the sound insulation of the earmuffs better than the 3m soundproof earplugs?"
Some people see that the price of 3m earplugs is much more than that of earmuffs. Because of the concept of "no good goods for cheap," it is mistaken for 3m earplugs to be better than earmuffs. The actual use results show that which of them is better depends on whether the specifications of the appliance are applicable to the user. When using earmuffs under what circumstances, earplugs under what circumstances should be determined according to the specific circumstances. If the crew should wear dust masks or goggles at the same time, it is best to use earplugs.
"I don't want these protective gears. I'm used to noise."
Human hearing organs are not accustomed to noise. If you are really "accustomed to" it means that hearing loss begins - the performance of hearing fatigue. Repeated noise exposure will not make your auditory organs stronger, nor will your remaining hearing loss continue. Although each person has a great difference in hearing-sensitive knowledge due to noise exposure, so far there is no standardized method to determine which people are sensitive to noise. Moreover, the harm of noise to humans is not only a harm to hearing, but also includes the systemic damage to the central nervous system, cardiovascular system, digestive system, etc. Wearing protective gear can reduce or prevent this harm, and why Not for it!
"Anyway, hearing is poor and you don't need to wear protective gear."
As long as there is strong noise that can cause hearing loss, there is no guarantee that your hearing will not diminish. As we all know, noise-induced hearing loss first occurred in the frequency band around 4 kHz. Later, it gradually expanded toward the low frequency direction, and finally affected the language listening frequency band (0.5 to 3,000). At this time, he found it difficult to talk. Although wearing 3m earplugs can not restore the hearing you have lost, it can prevent the further development of incurable deafness and prevent the development of permanent hearing loss (listening fatigue). .
"Put on protective gear and hear no one say it."
If the ears are subjected to strong noise, the auditory organs are overloaded and the hearing is disturbed, reducing its ability to discern different sounds. Wearing a 3m soundproof earplug reduces the noise level of all frequencies, thus enabling the ear to perform better.
