The graphs included below depict the sound pressure level maps resulting from grouping 8
generic point sources of sound, the centres of each separated by 56 cm.

source, varying as a function of frequency.
Comparison of the vertical coverage as compared with one single point source as a function of frequency.
Eight point sources of sound emitting in phase with the same amplitude.
