A method wherein operating a fan of a wearable head device; detecting, with a microphone of the wearable head device, noise generated by the fan; generating a fan reference signal, wherein the fan reference signal represents at least one of a speed of the fan, a mode of the fan, a power output of the fan, and a phase of the fan; deriving a transfer function based on the fan reference signal and based further on the detected noise of the fan; generating a compensation signal based on the transfer function; and while operating the fan of the wearable head device, outputting, by a speaker of the wearable head device, an anti-noise signal, wherein the anti-noise signal is based on the compensation signal.
