Patent number: 11386881Abstract: Active noise cancellation systems and methods include a feedforward path configured to receive a reference signal comprising ambient noise and adaptively generate an anti-noise signal to cancel the ambient noise and comprising an adaptive gain component configured to adaptively adjust a gain of the anti-noise signal, and a logic device configured to determine a leakage profile based on the adaptive gain component. The feedforward path includes a feedforward adaptive filter tuned to generate the anti-noise signal corresponding to the reference signal in accordance with the determined leakage profile. The leakage profile is selected from a plurality of stored leakage profiles that are tuned for a corresponding gain, and which corresponds to an ear coupling condition associated with a fit between the active noise cancellation system and a user. An adaptive transparency filter receives the reference signal and generates an ambient inclusion signal for output to a user.Type: GrantFiled: November 13, 2020Date of Patent: July 12, 2022Assignee: Google LLCInventors: Govind Kannan, Trausti Thormundsson, Jayvon Timmons, Wensen Liu

Patent number: 11026034Abstract: A self-calibration system may include a housing including a first calibration circuit configured to coordinate with a second calibration circuit to execute a calibration sequence for an active noise cancelling (ANC) earphone. The housing further includes a cavity configured to accommodate the ANC earphone, wherein the cavity is contoured to simulate the ANC earphone in a user's ear. The housing further includes a calibration microphone coupled with the first calibration circuit and configured to measure calibration sound waves from the ANC earphone, and a calibration speaker configured to emit calibration sound waves to the ANC earphone.Type: GrantFiled: October 25, 2019Date of Patent: June 1, 2021Assignee: Google LLCInventors: Govind Kannan, Wensen Liu, Jayvon Timmons
