Our Ears and How We Hear
... Use of a cotton bud or similar object to try and remove wax may cause injury and will only push most of the wax further into the ear canal. Consult a doctor if a blockage of wax occurs. Do not attempt to remove it yourself. Noise Prolonged exposure to loud noise can permanently damage hearing by cau ...

Earplug
An earplug is a device that is meant to be inserted in the ear canal to protect the user's ears from loud noises or the intrusion of water, foreign bodies, dust or excessive wind.
