What are ear plugs?
Ear plugs are devices which are designed to fit into the ear to muffle sound or to protect the ear from substances like water. A wide variety of ear plugs are on the market for an assortment of uses, ranging from protecting the ears of concert musicians to keeping water out of the ears of professional swimmers. Many drugstores sell ear plugs, and they can be a very good thing to keep around the house, because one never knows when ear plugs might be useful. Ear plugs can be made from foam, plastic, rubber, silicone, and other soft materials. To wear ear plugs, people gently flatten the ear plug by rolling it between their fingers, and then insert the ear plug into the ear, holding it in place while it expands to fill the ear canal. This creates a seal which can muffle noise or keep water and dust out of the ear. When it’s time to remove an ear plug, the end is gently pulled down to break the seal, allowing the ear plug to pop out.
