Lesson 6 Hearing protection

  • Exposure to noise may affect your hearing. There are laws that precisely define when the hearing protection should be used, setting personal noise exposure limits. As you may remember from the Module 1, the health effects resulting from exposure to noise can be of long-term character or can cause immediate hearing damage.
  • Earmuffs – plastic cups with isolating cushions, held firmly by headband.
  • Helmet-mounted earmuffs – same as above, but instead of headband, the earmuffs are mounted directly on the helmet
  • Earplugs – these are devices worn directly inside your ear, made of different materials; they may be equipped with holding cords or bands; they may be also custom-made and moulded to perfectly fit shape of individuals’ ears.

  • Following manufacturer’s instructions. You should always get familiar with operating manual prior the first use and in every case you have doubts about proper use of specific piece of equipment.
  • Proper fitting. It is important to properly adjust earmuffs or earplugs so that they provide the best fit your ears, efficiently limiting the sound getting to your ears. You can check if the fit is proper by placing hands over earplugs in your ears and when the sound is changed, there is something wrong with the fit. Unless the user manual says differently, normally earmuffs are not designed to be worn over hats or hoods.
  • Checking for any damage in structure of protective device before using it.
  • When you are in a noise environment, you should wear hearing protection all the time. The level of effective protection depends on the actual time with PPE in use.
  • Manufacturer’s recommendations regarding maintenance and storage should be followed.
