Strutt|Propagation|SEL from Moving Point Source inserts the Sound Exposure Level (SEL) from a moving point source into the active row of the worksheet.
The SEL from a moving point source is calculated by:
`SEL = L_max+10log_10((Kr)/V)`, where `K <= pi`
For an omnidirectional source, `K=pi`
A value of `K = 1.83` is suggested for aircraft noise. For diesel locomotives, the directivity characteristics of the source lead to a maximum value of 2.0 for `K`.
`V` is the velocity of moving point source.
`r` is the distance to the receiver.
