Noise Pollution • The harmful & unwanted sound of sufficient intensity to damage hearing. • Hearing impairment rarely leads to total deafness, however the hearing loss is permanent. • Decibel: unit used to express the relative intensity of loudness of sound. Normal conversation is 65 decibels • Exposure to noise levels of 85 decibels and above can result in temporary hearing loss often accompanied by ringing in the ears
NOISE INDUCED HEARING LOSS • Attending noisy concerts & clubs • Using firearms, loud tools & recreational vehicles (snowmobiles & some motorcycles) TRICKY PART IS THAT YOU DO NOT KNOW OF DAMAGE EARLY ON - IT TAKES MULTIPLE EXPOSURES & SOMETIMES YEARS TO FIND OUT - 10-20 yrs.
