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.

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).
