Claim 11:
12. A fire suppression nozzle, comprising:
a first conduit comprising an inlet and an outlet and configured to be coupled to distribution piping and receive an inert gas;
a second conduit coupled to the first conduit, the second conduit 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, wherein the first plurality of outlets and the second plurality of outlets provide a plurality of second flow paths orientated perpendicular to a first flow path between the inlet and the outlet;
a first sound absorbing member positioned on a first side of the outlet;
a second sound absorbing member positioned on a second side of the outlet;
wherein the first sound absorbing member and the second sound absorbing member reduce a sound power level of the inert gas after existing the outlet, and wherein each of the first sound absorbing member and the second sound absorbing member comprise:
a support plate; and
a sound absorbing insert, wherein the sound absorbing insert is composed of a sound absorbing material;

wherein the first conduit and the second conduit are configured such that the inert gas exits the outlet in a first direction and is directed in a second direction perpendicular to the first direction prior to a first portion of the inert gas exiting the first plurality of outlets directly to an external environment surrounding the nozzle and a second portion of the inert gas exiting the second plurality of outlets directly to the external environment;
wherein the inert gas is prevented from exiting the second conduit to the external environment within the middle portion, and
wherein a first volume of the first portion of the inert gas and a second volume of the second portion of the inert gas are substantially equal.
