this is a hack made to my hjc rpha max. is a modular helmet.
it have been made quieter, the vents are also quieter when open. i am using memory foam. cut into strip and is being place in the gap between the EPS and the shell. the air coming in from vent travels in between the shell and EPS liner causes noise.
try this
