Abstract
In the active pneumatic mount disclosed herein, a bellows or other flexible sealing means is utilized for containing a volume of pressurized gas which supports the weight of the equipment which is to be isolated. Within the pressurized volume is a means defining a chamber having an opening for receiving an acoustic transducer. An acoustic transducer is mounted in that opening for generating, in the pressurized volume, oscillatory pressure variations which reduce dynamic pressure variations induced by the vibrations which are to be blocked. The space within the chamber is vented to the pressurized volume, thereby to equalize the static pressure in the space.
