   Um, are you sure about that?  The white noise contains all audible 
frequencies, can one feel it that easily?  I have many times been on the 
stage of a rock concert when the sound system was tested.  I readily feel the 
bass system being tuned, but when they put on the white noise, I don't 
remember feeling any particular vibration.  I always assumed it was because 
it was so inclusive.  Anyhow,  maybe you would't need to add noise.  My point 
was that if you take the aural signal out, so that only the tactile feedback 
through the key was left, I would be surprised if one could tell the hardness 
of the hammer by what the finger receives.

Please do so and let us know.  I would think that the head against the piano 
body is a lot more entrained than the finger on the key!
