• Enclosures are devices that completely encompass the employee's head, much like the helmets worn by jet pilots.
• Earplugs (also known as aurals) are devices that fit into the ear canal. Custom-molded earplugs are designed and molded for the individual employee. Premolded earplugs are generic in nature, are usually made of a soft rubber or plastic substance, and can be reused. Formable earplugs can be used by anyone. They are designed to be formed individually to a person's ears, used once, and then disposed.
• Superaural caps fit over the external edge of the ear canal and are held in place by a headband. Earmuffs, also known as circumaurals, cover the entire ear with a cushioned cup that is attached to a headband. Earplugs and earmuffs are able to reduce noise by 20 to 30 decibels. By combining earplugs and earmuffs, an additional three to five decibels of blockage can be gained.
