Hearing Protectors

As you are probably well aware, there are basically four types of hearing protectors.

  • molded earplugs
  • custom-molded earplugs
  • self-molded earplugs
  • earmuffs
Are those dust masks hiding behind the hearing protection? Another OSHA citation!

Molded earplugs are usually made of plastic or silicone rubber. They are available in a variety of shapes and sizes and are usually characterized by one or more ribs or contours. They are considered multiple use; therefore, they must be cleaned and properly stored after each use.

Custom-molded earplugs are generally made of plastic and are designed from a molded wax insert of the wearer's ears. They are considered multiple use but cannot be switched ear to ear.

Self-molded earplugs are generally made of mineral down or plastic foam and are molded or formed by the wearer. Generally one size fits all and they may be either single or multiple use.

Earmuffs are designed to be multiple use and may be designed to be worn with the harness over or behind the head, or under the chin. They are generally more comfortable, but usually provide less noise reduction, thus less protection, than ear plugs.

What's best?

You might be wondering which type of hearing protection is best. It really depends on the nature of the noise. The best way to find out is to give both a try and see which one works best for you. If you want the best protection, wear both types together!
