Hi Mike and the Group
The wall clock does indeed have a second hand. I've placed it to my
ear and some of the "tocs" do indeed have a resonance about them which
i can hear with the clock face hard against my ear (my family now more
than convinced the old guy has lost his marbles). I cannot hear the
resonance when the clock is placed 1 to 2 feet away.
I will investigate further when I have a quiet house again (grand
chilren loose at the moment). Next time a smaller, less resonant,
room will be used. This week's test was in an "L" shaped room with
the two longer axes measuring 26 feet.
The mics were a matched pair of NT1As.
The original files are some 7 to 9 minutes long of 16/44.1 WAV -
between 70 and 110 MB each file. I will trawl then to see if the
resonance is somewhere there on the NH1 file.
Cheers
