Loud noise and hearing loss
It is a mistake to believe that only noises loud enough to cause earache are capable of causing damage. The inner ear can still be harmed by noise, even when it doesnt send you a pain signal. A rule of thumb is that if you need to shout to be heard over the noise, its potentially damaging. Suggestions on how to protect your ears from noise include Avoid exposure to noise when you can.
Consult with your occupational health and safety officer at work if you are concerned about noise levels in the workplace.When unavoidably exposed to loud noise, wear personal hearing protection such as earplugs, ear muffs or both. Wear earplugs in noisy environments, such as discos, rock concerts or motor racing events.Remember that everyday equipment, such as lawnmowers, power tools and personal stereos, may be loud enough to be damaging your ears.
