Sound level measurements in decibels are generally referenced to a standard threshold of hearing at 1000 Hz for the human ear which can be stated in terms of sound intensity: or in terms of sound pressure :

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 is easier to measure compared to Sound Power Level, which explains why NVH requirements of electrical machines are sometimes given in Sound Pressure Level.

The following equation is used to calculate a sound pressure level. dB = 10 * log (p^2 / pr^2) Where dB is the sound pressure in decibels P is the sound pressure (pascals)

A-weighting applies to sound pressures levels up to 55 dB, B-weighting applies to sound pressures levels between 55 dB and 85 dB, and C-weighting is for measuring sound pressure levels above 85 dB. In order to distinguish the different sound measures, a suffix is used: A-weighted sound pressure level is written either as dB A or L A. The general decibel formula for sound pressure level (SPL) is obtained by replacing all of the intensity values with the corresponding values of pressure squared because (I ≈ p 2).

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.

The manufacturer records sound pressure levels at fixed distances around the generator set and averages them to calculate the levels. It is critical to calculate the logarithmic mean of the measurements, not the arithmetical mean, to avoid having the generator set appear quieter on paper than in practice.
