Most noise level parameters in a report are based upon an SPL, albeit they are mostly adjusted in some way, i.e. weighted to a single number (dB(A)), or a level difference such as a Dw. A sound power level (SWL) is theoretical.

When measuring sound, we use the following logarithmic formula to determine the sound pressure level (SPL) in decibels. Here p is the sound pressure we are measuring, and Pref is our reference, the pressure of the smallest sound we can hear, 2.0×10 -5 Pa (you remembered this, right?).

Sound pressure level calculations are the same as sound power level calculations detailed above, except the 20 log(p/po) factor applies, instead of the 10 log(w/wo) ratios. For example to convert the 60 dB sound pressures to the p/po levels type 10^(60/20) into Google and the answer is 1,000. Repeat this procedure for the 70 and 61 dB levels.
