Safety Ear Plugs

Earmuffs are objects designed to cover a person's ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears.

Is it safe to wear earplugs every night?

However, disrupted sleep may also be a problem when trying to sleep in different environments, such as on a plane. Earplugs can significantly reduce the amount of sound entering the ears, which may help people get to sleep in noisy environments.
