1. It is better to use soundproof earplugs than soundproof earmuffs for the following reasons: 1. It is better to use soundproof earplugs when sleeping, because wearing earmuffs can only take a sleeping position, not sideways, and the casual comfort is definitely not as good as earplugs. But if you want to use earplugs, you need to choose memory cotton material with slow resilience. The earplugs made of this material have the best comfort, and the foreign body sensation is not strong when sleeping. Therefore, it is recommended to choose zero-listening anti-noise and sleep-guarding earplugs, which can give you a good experience of comfort and sound insulation. 2. It is better to use sound-proof earplugs than earmuffs in noisy places, because the sound-proof effect of excellent sound-proof earplugs is definitely better than that of sound-proof earmuffs. If it is a particularly noisy place and a high decibel working environment, it is best to use soundproof earplugs. It is recommended to choose sponge earplugs, which are comfortable to wear and have a sound insulation effect of 25dB-40dB, but it is not recommended to wear them for a long time, which is very irritating to the ears. If the ambient noise is around 26bB, soundproof earplugs will be used. Precautions for using sound-proof earplugs: When inserting earplugs, the air pressure in the middle ear will rise, which will press the eardrum and cause pain. This is because the earplugs are inserted too deeply. To avoid this danger, please carefully rub the earplug and insert it into the preset ideal position. When the earplug is completely expanded, it is best not to push it in. On the other hand, in order to avoid squeezing the eardrum when pulling out the earplug, the earplug should be turned out slowly, and no force should be applied. And pay attention to cleaning ears and earplugs regularly.
