reference, the individual standing at the far side of the gym is my 6'6"
tall good friend, John Nipps.

The gym has relatively good natural 'north' lighting due to the windows in the scalloped ceiling.
On both occasions at the gym to date, the temperature inside it has remained at 67-68 degrees Farenheit during the entire day-long sessions.
On Sundays, with the Soft Drink machine in the lobby area unplugged, the noise level in the gym is very low.
The gym exhibits the expected 'slap echo' problem, given its size and
the hard surfaces, but for measurement purposes the (using the 1.9KHz
high-resolution low frequency sampling rate) the usable 'window' of data
is about 70mS at 1m distance, reducing to ~48mS at 8m distance measurements. These times are exceptionally long compared to what I've been able to access in other venues.
The equipment bench setup for the January 2, 1998 measurement session. The
problem of limited length cables arose on that date, which kept distance
measurements limited to 7 meters then.
A line is created on the diagonal with masking tape and meter intervals
are marked off for repeatable distance measurements.
