In the active pneumatic mount disclosed herein, a bellows or othe flexible sealing means (29) 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 (30) having an opening for receiving an acoustic transducer (45). An acoustic transducer (45) 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 (43) is vented to the pressurized volume (30), thereby to equalize the static pressure in the space.
