Certification Part 1Participant ManualSection 5: Health and Safety Hazards127© Public Services Health and Safety AssociationHearing LossNoise may tire out the inner ear, causingtemporary hearing loss.After a periodof time away from the noise, hearing may be restored. With continued noiseexposure, the ear will lose its ability to recover from temporary hearing lossand the damage will become permanent.Permanent hearing lossresults from the destruction of cells in the inner ear,cells which can never be replaced or repaired. Such damage can be caused bylong-term exposure to loud noise or, in some cases, by short-term exposure tovery loud noises.How intense noise must be before our hearing is permanently or temporarilydamaged depends on the level of sound, the length of time we are exposed toit, the number and length of recovery periods between exposure times and, ofcourse, our personal sensitivity and tolerance for sound.Types of NoiseContinuous NoiseContinuous noise is constant noise to which an employee is exposed.Examples of continuous noise include:A worker operating a grader for 6 hours a dayA maintenance worker working in the boiler roomA busy call centreFigure 11: Continuous Noise Sound Wave
