Around 60x40 horizontal x vertical -6db


Hmm, if you go by standard outline on an isobar, your -6dB point is the middle orange (117dB) which gives you these…



But there are a fair few lobes… have you got it on 1/3rd oct smoothing?

There is no smoothing. This one is made with high precision.
48 frequencies from 100 to 6000 hz. So like:

Values between are aproximation on the colored chart. If I zoom in the spl graph there are straight lines between values.
Mesh frequency is also very high.


Those lobes from beamwidtch(coloured) chart you can see on off axis spl charts on large angles.

Okay but for comparison purposes, most isobars are shown at 1/3 oct so it’s useful to show
