Get a couple of pieces of egg-crate foam and glue them to the wall
behind the noisemaker. That will cut down on the focusing effect.

You might spray them with some kind of snow-flock stuff, but the
solvents could attack the foam, so check the labels and stuff.

As far as needing the oil for your grinder, maybe poke a hole
in an old sock and put it around the grinder to catch the spray?

Good Luck!
