Abstract:
An off-head detection system for an in-ear headset comprises an input device that receives an audio signal, a feed-forward microphone signal, and a driver output signal; an expected-output computation circuit that predicts a value of the driver output signal based on a combination of the audio signal and the feed-forward microphone signal from the signal monitoring circuit, and off-head data from the off-head model; and a comparison circuit that compares the observed output signal provided to the driver and the computed expected output to determine an off-head state of the in-ear headset.

Claim (Index 1):
A control system for a listening device, comprising:\n a detection system that reconfigures parameters in response to a detection event; an active noise reduction (ANR) circuit that manages at least a feedback-based noise reduction function, and an off-head monitoring circuit that compares an actual driver output signal and a predicted driver signal to determine the detection event, the detection event including a state transition between an on-head state and an off-head state of the listening device.
