Moving Point Source SEL Pass-By    1/1

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(K_r/V), where 0 <= K_r <= pi

For a completely directional source, K_r=0; for an omnidirectional source, K_r=pi
A value of K_r = 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_r.
V is the velocity of moving point source.
