I think that's the weakest point--where a distinction in noise level
of perhaps one or two dB is being made, trying to match clock ticks
by ear is too chancy for me. I suggest a 1 KHz tone from a speaker
between the clocks for level matching, calibrated by measuring
voltage at the speaker terminals. You can leave it out of the
published movie.
