Abstract (en)
A wearable audio device can include at least one speaker; a first sensor configured to sense sound related to the at least one speaker and provide a first sensor signal; a second sensor configured to sense sound external to the wearable device and provide a second sensor signal; active noise cancellation (ANC) circuitry configured to provide at least a third signal and fourth signal, wherein the third signal is a music compensated first sensor signal and the fourth signal is an ANC signal; at least one active vent; and at least one processor configured to: receive the first sensor signal, the second sensor signal, the third signal and the fourth signal to determine whether a trigger threshold is met, and if the trigger threshold is met, send a control signal to the at least one active vent to cause the at least one active vent to open or close.
