A microphone’s random (diffuse) inci-
dence response can be approximated by
measuring the 90º incidence response
relative to a single sound source (as per
B&K literature).
The diffuse field response is not easy to
measure, because it is not easy to gener-
ate a truly diffuse sound field over a wide
frequency range but there is a known
procedure to estimate the diffuse fre-
quency behavior of a free field micro-
phone.
