[DeTomaso] Dynamat Xtreme results - electric motor whine

[Larry - Ohio Time Corp]

Will,

I am down to my gold fish, Goldie 7 years old, what a gal. Most of my pumps
made there noise from there feet (fins?). I placed them on hard foam pad to
cut 50% out. If you feel comfortable putting a box over it (heat and air
circulation and all) normal foam packing that looks like egg cartons works
very well.

Is this the best stuff to muffle electric motor whine?

I'm trying to quiet down aquarium pumps.
