Pond Boss Forums AERATION Systems questions aerator noise

I recently purchased a Vertex aeration system which has been running for a little over a month now and it has performed wonders for the pond. No more thermocline, a boost in available nutrients which have caused a (first time in 20 years) green tinge from a sustained plankton bloom, and more useable habitat area for the fish.
The problem is the noise, the pump, in the manufacturers metal enclosure is located 150 feet from tne house and on the edge of a dense wooded area. The noise (54 dB at 100 feet) is probably a combination of vibration and some effect of the sound not penetrating the woods and boncing back towards the house. In any event it's noisy and the wife's not happy.
I'm considering housing the Vertex enclosure in a plywood enclosure with sound deadening accoustic foam and of course screened vents. Has any one had any experience building any sound enclosures for aerator compressors or know where I can come across any plans or suggestions.
