LAeq : it is good practice to include other measurement parameters, such as
A-weighting, so other people are aware of how the measurement was made; other examples include:-
LAeq,t : A-weighted equivalent sound pressure level in dB measured over a period of time t.
LCeq,t : C-weighted equivalent sound pressure level in dB measured over a period of time t.
Short Leq : the preferred modern method of storing sound levels and displaying the true time history of noise events and all other sound levels during any specified period of time. The resulting 'time histories', typically measured in 1/8 second intervals may then be used to calculate the 'overall' levels for any sub-period of the overall measurement time.
