A FLEXIBLE SIZE DIFFUSER GRID ASSEMBLY FORMED UP OF INDIVIDUAL SPARGER UNITS (22) FOR USE AS A NOISE ABATEMENT DEVICE TO REDUCE THE FLUID PRESSURE IN A PREDETERMINED MANNER TO SUBSTANTIALLY REDUCE THE AERODYNAMIC NOISE AND STRUCTURAL VIBRATIONS PRODUCED BY A FLUID MOVING THERETHROUGH. THE SPARGER GRID ASSEMBLY IS FORMED IN A WINDOW PANE GRID-LIKE ARRANGEMENT OF INDIVIDUAL SPARGER PANE UNITS, EACH OF WHICH ARE MOUNTED IN A SUPPORT FRAME, AND EACH OF WHICH UTILIZE INDIVIDUAL STACK OF FLAT PLATES (39), THE PLATES RESPECTIVELY HAVING INLET SLOTS (40) AND OUTLET SLOTS (42), AND INTERCONNECTING PLENUMS (44), TO CREATE A SERIES OF PASSAGEWAYS (46) TO SUBSTANTIALLY SUBDIVIDE THE FLOW STREAM OF STEAM INTO SMALLER PORTIONS TO REDUCE FLUID PRESSURE. THE INDIVIDUAL SPARGER UNITS CAN BE FORMED OF A STANDARD SIZE, OR INSTEAD FORMED OF CUSTOM SIZES, AND GREATER OR LESS NUMBERS OF INDIVIDUAL WINDOW PANE SPARGER UNITS CAN BE USED IN THE FRAME, DEPENDING ON THE GIVEN END-USE APPLICATION.
