WebDecibel is one tenth of a bel, so 1 bel is equal to 10 decibel: 1B = 10dB Power ratio The power ratio in decibels (dB) is 10 times base 10 logarithm of the ratio of P 1 and P 0: RatiodB = 10⋅log 10 ( P1 / P0) Amplitude ratio The ratio of quantities like voltage, current and sound pressure level are calculated as ratio of squares. Webidle operation of the machine was 12.1 dB (A). The difference between the highest and the lowest noise levels is 11.1 dB (A). The minimum noise level measured during idle operation of the machine is in the range of 63 to 75.1 dB (A), while the minimum noise level during processing of the metal material is in the range of 67 to 78 dB (A).
