The decibel scale is logarithmic, meaning it increases by the power of 10 each time. A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels. Decibels make the numbers much easier to work with. You have probably already seen from each decibel chart that anything over 80 dBs(more specifically 85 dBs) can cause severe problems over time.
