Abstract
A seal assembly for canal hearing devices including a dynamic pressure vent formed and defined by diaphragmatic flaps configured to open in response to a pressure gradient across the diaphragm. The seal assembly comprises a compliant seal element configured to be positioned generally concentrically around the canal hearing device for providing comfortable contact with the ear canal and for acoustically sealing the residual volume of the ear canal. The seal assembly is preferably made of an elastomeric material. The dynamic pressure vent is substantially closed in the normal position to minimize feedback, while momentarily opening inside the ear canal during insertion or removal of the canal hearing device into or from the ear canal.
