Abstract
A noise reduction method and a noise reduction apparatus are provided. The noise reduction method is applied to a keyboard of an integrated terminal device, and the noise reduction method includes: obtaining a first voice source and a second voice source, where the first voice source is a fidelity voice source, the second voice source is an audio signal that includes the first voice source and a noise signal, and the noise signal comes from noise generated by vibration of the keyboard, and/or the noise signal comes from noise of an environment in which the integrated terminal device is located; determining the noise signal based on the first voice source and the second voice source. Based on the technical solutions in this application, the noise signal generated by the integrated terminal device can be offset, so that noise reduction processing is implemented and user experience is improved.
