Doing some test runs to identify various noises in the Frequency Spectrum when whatever it is that causes this noise problem is at its most quiet.
The idea is to do the actual noise measurements when it is at its loudest (usually but not always from Friday evenings to Saturday mornings) and then see if there are any correlations between the very disturbing noise (which will hopefully register then) and low frequencies.
I will probably have to do many such measurements before figuring it out.
