Abstract
Systems and methods are disclosed for avoidance of user discomfort due to pressure differences by vent valve. In one embodiment, a method for equalizing air pressure in ear canal includes sensing a pressure difference between a pressure in ear canal (PEC) and an ambient pressure (PAMB) by a sensor of a hearing device. Based on sensing the pressure difference, an active valve is set to a first position to open a vent through the hearing device or to a second position to close the vent through the hearing device.
