3 Ways to Measure Decibels
3. Take the Log10 of your answer and multiply by 10. To finish solving, all you need to do is take the base 10 logarithm of your answer, then, finally, multiply by 10. This accounts for the fact that decibels are logarithmic units with a base of 10 — in other words, an increase of 10 decibels means that the loudness of the sound has doubled.
