No, you forgot that the d stands for deci (i.e., 1/10th). So 240dB is 10^(2.4-1.3) times as much sound power as 130dB.

- vonmoltke 11y agoNo, nitrogen's math is correct. The conversion from linear to dB is y = 10 * log(x) and the conversion back is x = 10 ^ (y/10) Every change of 3dB is a doubling or halving of power. Every change of 10dB is an order-of-magnitude change in power.
