A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. For example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180. But 93 dB is still twice as much noise as 90 dB. In other words, sound intensity doubles every 3 dB.
