No no , I meant the front rail punching and I will quote my own words
otherwise I'll have to type it all over again.

quote :

"Why does a tone get louder when you replace the front punching with a more
dense one?
We have to compare it with a seasaw on which two little children sit.

One child pushes off from the ground, the other hits the ground.
The ground is soft because it is sand so the impact is not painful.
OK..I can see that you already got it.
Now we replace the sand...it is hard cement. The child coming down hits the
cement BAM! it hurts! and the other child on the other end of the the seasaw
is almost catapulted off  into the sky.
The difference lies in the hardness of the ground, which, in our case is the
front punching.

The opposite takes place as well but is a bit more dampened by the different
action parts absorbing the blow of the hammer against the string.
Also, the hammer blow against the string causes overall vibrations
throughout the whole instrument resulting in vibrations we can perceive with
our sensitive fingers, just like you can feel the vibrations if you put your
hand against the side of the grand."
