Abstract
A technique for rotational correction of a microphone array includes generating first audio signals representative of sounds emanating from an environment and captured with an array of microphones of an ear-mountable listening device; identifying a characteristic human behavior having at least one of a typical head orientation or a typical head motion associated with the characteristic human behavior by monitoring sensors mounted in fixed relation to the array of microphones; determining a rotational position of the array of microphones relative to the ear based at least in part upon identifying the characteristic human behavior; applying a rotational correction to the first audio signals to generate a second audio signal, wherein the rotational correction is based at least in part upon the rotational position; and driving a speaker of the ear-mountable listening device with the second audio signal to output audio into an ear.
