Eight different ear plug materials were tested, in 5 ears each, in artificial shallow underwater conditions for 30 minutes, in order to determine their efficacy in sealing the ear canals to avoid water-borne infections in ear canals and open middle ears. Most of the plugs tested would meet everyday requirements for protection, but the polymeric foam plugs, treated with petroleum jelly, and moldable plastic materials were most effective in protecting both the middle ear and the ear canal skin.
