Dan,
There was a post on my forum a while back on the vibration the air pumps
make. They haven't gotten much quieter, but there were some unique
suggestions on how to silence them a bit. =)
There are other options rather than air pumps and sponge filters, sponges
attached to a power head can also be beneficial. Also, the output from a
power head can be directed to stop debris from settling on the gravel to
make your mechanical filtration work better. So there's another option for
you. There's always the option of adding filters with biowheels, etc too. It
all boils down to how much you want to spend. Again, this should all be
balanced against tank size and fish load.
