Did you know that hearing does not regenerate? Hearing damage is irreversible. A hearing aid can, at most, compensate, but will never restore a person’s hearing. Someone subjected to 100 dB (noise of a lawnmower) for 40 hours a week, after 20 years, will, on average, experience a 48% hearing loss. Through this online training, the worker will be made aware of the importance of using adequate hearing protection to preserve their hearing health.

Target Audience

Any worker who is likely to use hearing protection.


  • Describe the properties of sound
  • Describe the anatomy of the ear
  • Describe how the ear interprets sound
  • Differentiate noise types and understand their impact on hearing
  • Describe hearing loss and how to prevent it
  • List the requirements of a hearing conservation program
  • Compare the advantages and disadvantages of ear muffs versus ear plugs
  • Identify noise hazards and select the appropriate protection
