  • Pressure regulating earplug
    Patent number: 6820717
    Abstract: An earplug is provided for use by an airplane passenger, which more slowly increases the pressure of air in the passenger's ear canal than the rate of increase in cabin air pressure as the airplane descends near the end of a flight. The earplug has a cavity (30) that is open to the front end (20) of the earplug, and with a restrictor (24) at the front end of the cavity that allows air to pass between the cavity and ear canal, and the cavity to collapse, only at a very slow rate. As the environmental air pressure increases near the end of a flight, the earplug is slowly compressed in diameter and compresses the cavity.
