summation is over all samples i in the region.
| n | is the number of samples included in the summation. |
| Ei | is the linear Sv of sample i (m2/m3) - set to 0 for any sample where Ei < mSv or Ei > MSv, |
| En | is the observed Mean Energy of the region in linear units (m2/m3) = 10Sv/10 |
| mSv | is the minimum integration threshold (dB re 1 m-1) at time of processing. |
| MSv | is the maximum integration threshold (dB re 1 m-1) at time of processing. |
| ESD | Standard_deviation (Standard Deviation of the Energy)

All symbols are as defined in the nomenclature developed for SHAPES algorithms.
