that distance and angle. But how do you test a microphone in the
first place? What is the source?

You need items:

sound dead room

reference microphone

compressor with side-band input

device under test

poweramp

data-recording device

As alternative sound source I vaguely remember something about a spark being
used because its real world response tends to mimic the theoretic reasonably
well.
