Abstract: Embodiments include a wearable electronic device including a housing having an internal wall separating an internal chamber from an external chamber, an outer shell defining a port that connects the external chamber to an external environment, a membrane positioned at an opening in the internal wall and configured to equalize a pressure within the internal chamber with a pressure of the external environment, a first pressure-sensing device positioned in the internal chamber and configured to produce a first output, a second pressure-sensing device positioned in the external chamber and configured to produce a second output, and a processing unit configured to estimate the pressure of the external environment using the second output in accordance with a determination an accuracy condition satisfies a criteria and estimate the pressure of the external environment using the first output in accordance with a determination the accuracy condition does not satisfy the criteria.
