Abstract: A method of calibrating a feedback-based noise cancellation system of an ear device may involve obtaining a measured plant response of the ear device, obtaining a reference plant response value and determining a plant response variation between the reference plant response value and a value corresponding to the measured plant response. The method may involve obtaining a measured a coupler response of the ear device, obtaining a reference coupler response value and determining a coupler response variation between the reference coupler response value and a value corresponding to the measured coupler response. The method may involve determining, based at least in part on the plant response variation and the coupler response variation, a microphone signal gain correction factor and applying the microphone signal gain correction factor to ear device microphone signals that are input to a feedback loop of the feedback-based noise cancellation system.

Abstract: Embodiments are described for designing a filter in a magnitude domain performing an impedance filtering function over a frequency domain to compensate for directional cues for the left and right ears of the listener as a function of virtual source angles during headphone virtual sound reproduction. The filter is derived by obtaining blocked ear canal and open ear canal transfer functions for loudspeakers placed in a room, obtaining an open ear canal transfer function for a headphone placed on a listening subject, and dividing the loudspeaker transfer functions by the headphone transfer function to invert a headphone response at the entrance of the ear canal and map the ear canal function from the headphone to free field.
