Abstract

The present application provides a noise reduction control method and an electronic device, the method comprising: collecting a first sound signal of a first sound source at a position whose distance from at least one first sound source is less than a first preset distance; Acquiring a second sound signal at a position less than the second preset distance; obtaining a third sound signal corresponding to the first sound signal in the second sound signal; generating a fourth sound signal based on the third sound signal, the fourth sound signal and the first sound signal The phases of the three sound signals are opposite or the same; and the fourth sound signal is output through the audio output device. The noise reduction control method and electronic equipment provided by this application enable the user to clearly hear the sound they want to hear by canceling the sound generated by the interference source or enhancing the sound generated by the sound source that the user wants to receive, and the user experience is better. it is good.

Description

technical field [0001] The present application relates to the technical field of audio control, in particular to a noise reduction control method and electronic equipment. Background technique [0002] With the development of society, people's lives are becoming more and more crowded, and in some occasions, they will be interfered by various sound sources, and cannot concentrate on listening to a specific sound. Therefore, users usually want to keep a specific sound and eliminate the interfering sound . For example, when listening to music, there will be animals, babies, or noise from a construction site. Contents of the invention [0003] In view of this, the present invention provides a noise reduction control method to solve the problem that users will be disturbed by various sound sources in some occasions and cannot concentrate on listening to a specific sound. The technical solution is as follows: [0004] A noise reduction control method, the method comprising: ...
