Quiet Library
*Every increase of 10 dB(A) (decibels) is equal to a 10-fold increase in sound intensity. A 20 dB(A) increase raises the sound intensity by 100 times, a 30 dB(A) increase raises the sound intensity by 1000 times, and so on. The dB(A) representation is shown in the figure above. The values are sourced from internal test results and are for reference only.
