Claim 16:
17. 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 and a second portion of the inert gas exiting the second plurality of outlets; and
wherein the inert gas is prevented from exiting the second conduit to an external environment surrounding the nozzle within the middle portion, wherein during discharge of the inert gas from the first plurality of outlets and the second plurality of outlets, the first sound absorbing member and the second sound absorbing member reduce the sound power level to less than 125 dB for a frequency range from 500 to 10,000 Hz.
