Harmful Noise Levels


Harmful Noise Levels

Loud/harmful noise levels play a large role in damaging your hearing. Some individuals are more sensitive to certain sounds than others depending on the frequency level of that particular noise. Frequency in sound determines how low or how high a tone is; which are measured in decibels.

Noise Levels (in decibels):

Average threshold of hearing
15
Soft whisper, leaves rustling, soft music
30
Average at home noise/ quiet office
40
Normal conversation, background music
60
Noisy office, inside a car at 60 mph
70
Vacuum cleaner, average radio
75
Traffic, noisy restaurant
80
Window unit air conditioner/grinder
85
Heavy truck/subway/ orchestra
90
Lawn/power mower/ jack hammer
95
Boom box, ATV, motorcycle/crane
100
Chainsaw, leaf blower, snowmobile/bulldozer
105
Rock group/band
110
Snowmobile, pile driver
115
Jet taking off
130
Shot gun blast
140



A level 80 and below can be a usual eight hour day without using ear protection or causing damage.






Exposure over 80 decibels can cause temporary hearing loss which can lead to permanent damage with continuous exposure.





 Above 130 decibels may cause pain and instant hearing damage/loss.
