With standing trees and a nylon hammer yes. With lumps of wood I'm

I was thinking of 3 or 4 metre lengths of trunk that we could stand
up with the crane; they'd be reasonably stable but once everybody had
done their bit we could push them over, look at the butt and the top
and even
cut them up.
We could guy them if a risk assessment deemed it necessary.

Risk assessment is an issue of course, but I think not the main one. The
properties of dead, felled wood and live wood are very different,
particular with regards to sound transmission. And when you're
considering resonance the properties of part of a tree are very
different to the properties of a whole tree. The properties of a log on
end, a log on its side with shuttering over the ends and a log on its
side with out shuttering are all very different to each other, and in
turn completely different to a whole, growing tree. What you suggest
simply wouldn't be a realistic test of the ability of various methods
and practitioners to estimate the extent or location of sound wood in a
standing tree.
