Current dry earplugs for water activities (swimming etc.) create a .45lb psi pressure differential between the earplug and the ear drum for every 1' they are submerged below the surface, At 10' underwater there is nearly a 5lb psi pressure problem, seeking to rupture the tympanic membrane.

Employing one of the many new, medical, waterproof, tacky, skin safe, silicone adhesives with the flexible silicone flange section on the earplug guarantees a water tight seal on most users. This skin safe adhesive method of attachment is presently unique (and patented).
