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):

|
Soft whisper, leaves
rustling, soft music

|

using ear protection or causing damage.
Exposure over 80 decibels can cause temporary hearing loss which can lead to permanent damage with continuous exposure.
