My projector is placed on a shelf that is mounted to a very rigidly built drywalled box around some ducts. When touching the bottom of the shelf I can feel some vibration from the sound pressure being translated to the shelf. The projector (Epson 8500) rests on some rounded soft rubber pads and touching the projector I do not notice any vibration on the projector. So the pads are doing their job. My concern is that I can feel the vibration on the shelf when the music is played at very moderate wife acceptable level. At higher sound levels the vibration may be transferred to the projector degrading the picture (and probably decreasing the projector MTBF) . For this reason I am considering an extra layer of dampening by making a small platform out of a piece of hardboard resting on pieces of weather stripping foam. I will probably have to experiment with the amount and /or type of foam to get it into the right elasticity zone given the weight of the projector.
Has anyone had a similar problem to solve?
