An earplug is a device that is inserted in the ear canal to protect the user's ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Since they reduce the sound volume, earplugs are often used to help prevent hearing loss and tinnitus.
Is it safe to wear earplugs to bed?
Earplugs are generally safe to use while sleeping. However, it is possible that frequent use can lead to some minor problems in the long run, such as earwax buildup. Sometimes, noise from the environment can disrupt sleep.
Can you reuse earplugs?
Disposable foam earplugs may lose elasticity after a single usage; If reused they might not expand properly in the ear and would therefore offer less sound reduction than specified by the manufacturer. Reusable foam earplugs can be washed and reused multiple times without damage or lasting deformation.
Do earplugs expire?
The average lifespan of custom-made earplugs is 4 to 5 years
