摘要：
A pressure regulating earplug for regulating the rate of change of pressure inside an ear to minimize the pressure differential between the middle ear and a volume of the external ear cavity adjacent the ear drum is made of an ear plug adapted to fit tightly within the external ear cavity with no or minimal air leakage, and disposed within the earplug is a pressure regulator with a slow leak rate. Examples of the material which causes the pressure regulation include porous metal and porous ceramic material.
