Loud noise can cause many hearing problems. The damage to your hearing depends on how loud the noise is, and how often and for how long you are exposed to it. The way you hear noise may also change. Sounds may become unpleasant or seem louder than they really are.

To protect workers’ hearing, employers should:

  • test workers’ hearing before they start work and regularly during their employment.
  • test the noise level at work.
  • make changes to reduce noise.
  • provide earplugs and earmuffs if the noise level at work can harm workers.
