Dynamic pressure vent for canal hearing devices

A diaphragmatic pressure valve incorporated within a flexible seal assembly of a canal hearing device, the diaphragmatic pressure valve comprising 3 or more flexible flaps that are configured to be closed for acoustical sealing inside an ear canal during placement of the canal hearing device inside the ear canal, and wherein the flexible flaps are configured to temporarily deform and open upon pressure changes across the flaps.

A seal assembly for a canal hearing device, comprising:

• a compliant sealing element;
• and
• a membrane section in the complaint sealing element, wherein the membrane section includes one or more flaps formed in the membrane section, wherein at least one of the one or more flaps are configured to deform from a first position to a second position in response to a pressure gradient across the seal assembly while inside the ear canal.

A method for air pressure venting for a canal hearing device in-situ, the method comprising:

• creating an air pressure gradient across a dynamic pressure vent of the canal hearing device, by either insertion or removal of the canal hearing device into or out of the ear canal, wherein the dynamic pressure vent comprises one or more flexible flaps configured to be in a closed position during equal pressure across the flaps;
• and
• deforming the flaps to an open position responsive to the air pressure gradient, thereby allowing air flow and pressure equalization across the dynamic pressure vent.

A canal hearing device assembly comprising:

• a canal hearing device including a microphone, a receiver, and a power source enclosed within a housing;
• and
• a seal assembly removably attached to the canal hearing device and including a compliant sealing element and a pressure vent configured to open responsive to a pressure gradient between a first side of the seal assembly and a second side of the seal assembly.
