So, even though we may think that a 10 dB sound difference is negligible, it is, in fact, quite significant.ĥ0 dB is a moderate sound level, one that you can measure in a quiet residential area or a moderately quiet room. This is because the decibel scale is logarithmic, not linear, and describes progressing measurement changes. Imae By Canva Design 120 dB Comparison To Other Sound LevelsĮach time a sound’s level increases by 10 dB, its intensity also increases 10 times. In the decibel chart below, you can see a graphic representation of safe and harmful decibel levels (yellow sound levels are ok, red sound levels are harmful). The recommended exposure time decreases as noise levels exceed 85 decibels, which is the limit from which sounds are considered harmful to the human ear. For babies, the maximum decibel level they should be exposed to is 50-60 dB. Here are some examples of maximum recommended exposure times:Įxposure to sounds below 70 decibels is considered safe for human hearing no matter how long you are exposed to this level. It is important to note that 120 decibels is a noise level so extreme that it can instantly damage your hearing and being exposed to such loud noises for even a few seconds can cause irreversible hearing damage or hearing loss.įor the human ear, which is very sensitive especially to sound impulses, exposure to noise levels above 85 decibels becomes dangerous after 8 hours and the recommended maximum exposure drops each time there is the slightest increase in decibel level.
