tone sustain

A long-time client just moved up to a Boston upright.  I gave the piano
its second tuning.  I had never worked on one of these pianos...it's
pretty much like a Kawai (I think they build it) or Young Chang.

The only complaint from the owner is that the upper notes do not sustain
very long. It's apparently very noticeable to her and her paino
teacher.   

I wonder...if I were to voice the hammers down, would that help matters? 

My guess is that the hammers are so hard that the intial amplitude it
quite high (loud with lots of prominant upper partials). Then the decay
time (sustain), while being normal, appears shorter because the extreme
change in amplitude from very loud to soft happens so quickly.

I don't do much voicing, so I'm in above my head.

Thanks
