Abstract: This application discloses a sound masking method and apparatus, and a terminal device. When the terminal device uses a receiver as an output end of an audio signal, the terminal device determines, based on the audio signal, a masking sound signal, and then transmits the masking sound signal by using a speaker. The masking sound signal is determined based on the audio signal, and a difference between a distance from the speaker to a far field and a distance from the receiver to the far field is small. Therefore, the masking sound signal can better mask a leaked sound of the receiver and prevent information leakage in a call sound.
