Abstract
Aspects are generally directed to headphone systems that adjust Active Noise Reduction operations based on measurements of environmental conditions. In one example, a headphone system includes an earpiece having an interior volume, the earpiece configured to couple to an ear and define an acoustic volume including the interior volume and a volume within the ear, a speaker to provide acoustic energy to the acoustic volume based on a received driver signal, a feedback microphone to detect at least residual noise within the acoustic volume and generate a feedback audio signal indicative of the residual noise, and a control circuit including a sensor interface configured to receive an atmospheric pressure signal, the control circuit coupled to the feedback microphone to receive the feedback audio signal, and the control circuit configured to adjust the driver signal based at least in part on the feedback audio signal and the atmospheric pressure signal.
