Abstract

A system and method for a sensor-supported microphone includes an amplifier having an input configured to be coupled to a transducer, and an output coupled to an analog interface to output a transduced electrical signal from the transducer, a data bus configured to be coupled to an environmental sensor, a calibration parameter storage circuit coupled to the data bus, the calibration parameter storage circuit comprising calibration data relating sensitivity of the transducer with environmental measurements provided by the environmental sensor, and a digital interface coupled to the data bus and configured to output the calibration data and the environmental measurements.
