57AbstractABA microphone assembly comprises a substrate and an enclosure disposed on the substrate. A port is defined in one of the substrate or the enclosure. An acoustic transducer is configured to generate an electrical signal in response to acoustic activity. The acoustic transducer comprises a membrane separating a front volume from a back volume of the microphone assembly. The front volume is in fluidic communication with the port, and the back volume is filled with a first gas having a thermal conductivity lower than a thermal conductivity of air. An integrated circuit is electrically coupled to the acoustic transducer and configured to receive the electrical signal from the acoustic transducer. At least a portion of a boundary defining at least one of the front volume or the back volume is configured to have compliance so as to allow pressure equalization. The first gas is different from the second gas.
