Abstract

There are disclosed earplugs composed of certain polymeric foam materials. The earplugs are of generally cylindrical shape and of somewhat larger diameter than the human ear canal. The earplugs are composed of a foamed plasticised polymeric material having a sufficiently high concentration of plasticizer to provide the earplug with a reduced rate of recovery from compression.
