Ear plugs

An earplug is a device that is meant to be inserted in the ear canal to protect your ears from loud noises or the intrusion of water, foreign bodies, dust or as Wikipedia puts it  ‘excessive wind’!  Personally I have never heard a fart that loud but whoever wrote the Wikipedia entry presumably had, perhaps it was his – what an achievement sub-woofer farts!

There are apparently three types of earplugs for hearing protection:

  • Foam earplugs, mainly made of memory foam, which are compressed and put into the ear canal, where they expand to plug it.
  • Silicone earplugs, which are rolled into a ball and carefully molded to fit over the external portion of the ear canal, providing a snug custom fit for the user.
  • Flanged earplugs, including most types of musicians' or 'Hi-Fi' earplugs, as well as custom molds once they are molded.
