Claim 10:
11. A fire suppression nozzle comprising:
a first conduit comprising an inlet and an outlet;
a second conduit coupled to the first conduit and comprising a first plurality of outlets spaced apart from a second plurality of outlets along a length of the second conduit by a middle portion of the second conduit with no outlets;
a first circular sound absorbing member positioned on a first side of the outlet; and
a second circular sound absorbing member positioned on a second side of the outlet;
wherein the first conduit is configured to receive an inert gas at the inlet and provide the inert gas to an interior of the second conduit via the outlet at a location between a first end of the second conduit and a second end of the second conduit, wherein the location is aligned with the middle portion; and
wherein the first conduit and the second conduit are configured such that the inert gas exits the outlet in a first direction and a first portion of the inert gas is directed toward the first plurality of outlets in a second direction, and a second portion of the inert gas is directed toward the second plurality of outlets in a third direction opposite the second direction, wherein the second and third directions are generally perpendicular to the first direction,
wherein during discharge of the inert gas from the first plurality of outlets and the second plurality of outlets, a sound power level at the fire suppression nozzle is less than 125 dB for a frequency range from 500 to 10,000 Hz at a flow rate greater than 1,000 cubic feet per minute.
