Abstract
A sound signal processing method and a headset device. A target filter and a first audio processing unit are added. The target filter processes an external sound signal collected by an external microphone, to obtain an environmental sound attenuation signal and a voice attenuation signal. The first audio processing unit removes, based on the environmental sound attenuation signal and the voice attenuation signal, a second external environmental sound signal and a second voice signal from an in-ear sound signal collected by an error microphone, to obtain a blocking signal, and transmits the blocking signal to a feedback filter. The feedback filter may generate an inverted noise signal corresponding to the blocking signal and play the inverted noise signal through a speaker.
