Abstract
Nozzles (22) for reducing noise generated by the release of gas from a hazard suppression system (10) are provided. The nozzles (22) comprise a plurality of partitions (42, 44, 46, 48) that define a serpentine gas flow path through the nozzle. The flow path causes the gas to undergo a plurality of expansions and directional changes thereby reducing the velocity of the gas and dampening the generation of sound waves as the gas exits the nozzle (22) through the nozzle outlet (40).
