Answer 2

Answer:

4) 10:1 is the power ratio of one decibel.

Explanation:

One decibel (0.1 bel) equals ten times the power ratio's common logarithm. The intensity of a sound in decibels is expressed as 10 log10 (S1/S2), where S1 and S2 are the intensities of the two sounds; doubling the intensity of a sound represents an increase of a little more than 3 dB.
