Noise earplugs protect the ear from external noise, but also have some potential safety hazards. To buy earplugs and long-term use, pay attention to the following points:

First, identify good and bad

Slow rebound effect: too much elasticity, anti-noise earplugs expand the skin when pressing the external auditory canal, can cause ear distension, earache and other discomfort; the elasticity is too small can not be in close contact with the external auditory canal, the sound insulation effect is reduced. Therefore, the earplug's rebound speed must be observed. The longer the rebound time, the better the quality.

Softness: Softness directly affects the comfort of wearing earplugs

Surface texture: Some earplugs feel sticky and stick in the ear and stick to the skin of the ear canal. Avoid buying. The best way to discriminate is to stick the two earplugs tightly together and separate them to see if they are separated as quickly as possible.

Second, hidden dangers

The use of earplugs may cause cerumen to be pushed into the middle ear while the earplug is inserted into the ear canal, which can cause tinnitus, diminish hearing, pain or bacterial infection.

Users with excessive cerumen should use earplugs more carefully, and earplugs should often be washed with water and mild soap. However, foam-type earbuds are generally disposable and disposable, and soaking them in water may lose the slow rebound characteristics.

In addition, anti-noise earplugs may also be a trigger for otitis, because in warm, humid environments, many bacteria multiply more vigorously.

However, the use of noise-proof earplugs is generally safe, but the potential dangers that may arise from long-term use must be prevented: Insertion of the earbuds can cause the pressure of the middle ear to rise and push the eardrum to cause pain because the earplugs are inserted too deeply. To avoid this danger, first squeeze the earbuds into the ideal position, and when the earbuds are fully inflated, it is better not to push in. And vice versa, in order to prevent the ear drum from being squeezed when pulling out the earplug, the earplug should be slowly unscrewed and not pulled out.
