Abstract
A tinnitus suppression device using an in-the-canal external ear canal pressure regulating device to alter the pressure of the fluid of the external ear canal interior of the pressure regulating device. The device has a body which can be inserted into the external ear canal and which seals the canal from ambient pressure. An adjustably sized body such as a collapsible bulbous portion or a bellows type wall provides a mechanism for altering the pressure in the canal. Either a valve or a mechanical displacement device maintains the pressure differential created.
