Reducing Pile Driving Vibrations.
(OP)
Are there any known means or methods by which vibrations due to pile driving may be reduced?

RE: Reducing Pile Driving Vibrations.
In some circumstances, jetting or preboring can help. You may want to look thru some of the pile driving documents posted at the link below.

Is the problem with vibrations human perception or are you concerned that the vibrations will cause actual damage?
The obvious solution is to use augercast piles so there are no vibrations from pile driving.
I was recently involved with a job where piles were driven within 5 feet of an existing sewerline. Vibration monitoring was done and the actual vibrations were low enough that no action needed to be taken to reduce the vibrations. The piles were driven H-piles to rock and the soil above rock was loose to medium dense alluvial deposits. If vibrations were a problem, we were planning on preboring to loosen the soil and reduce the energy required to drive the piles.

A distance of 100 feet, the vibration at the structure would probably be less than 0.5 ppv, depending of course on the hammer and other factors.

I would try driving with a small vibratory and do some vibration monitering. If the results are not good you can try a pilot trench. If you still are not satisfied, you can switch to an impact hammer.
My feeling (with out knowing all he particulars) is that you will be okay with a small vibro.
