Product Description

Video and lesson investigations on the topic of hearing. Key concepts include:

  • Loud sounds can damage the hearing ability of ears.
  • Ear-defenders protect ears by cutting down the intensity of sound that reaches them.
  • Ears are sensitive organs and have limits to the amount of sound they can safely handle. Exceeding these limits can damage the ears, in some cases permanently.
  • Ears need to be protected from these risks where sustained and excessive sound is present.
  • The longer the exposure to excessive sound the greater the risk of ear damage. The eardrum or tympanic membrane), which vibrates as sound is carried to it, is very thin.
  • It is only able to tolerate vibrations to a set limit.
  • Sound that is too loud causes the eardrum to vibrate beyond its endurance and can make it rupture.
