Setting up a measurement is easy enough, its setting it up correctly so as
to issolate what one is looking for that presents the challange. One also
needs to know what signature the looked for signal has so as to be able to
properly idendify it. There has been some research done but most of this
pertains to the question of whether  a piansts varying touch can influence
tone. I have yet to be able to find an experiement that set itself to the
task of identifying through measurement if the impact can be felt at the
key.

There are also a few more impirical methods to attempt, but again for these
to have any meaning one simply needs to set things up thoroughly. For
example the testing to see whether a ear muffed person can identify hardness
or not by feel alone. I have done some informal testing and measuring, and
both point towards there being something delivered to the end of the key by
the hammer impact. But since I know the degree of control I have on such
experiment is far from sufficient to draw any conclusions on,... I dont. I
do want to pursue the matter tho. Its really quite interesting when it comes
down to it.
