Abstract: A feedback noise reduction method, a feedback noise reduction system, and an earphone are provided. In the method, a channel morphological parameter of an acoustic channel between a microphone and a speaker in a feedback noise reduction system is detected; the feedback noise reduction system is switched from using a first noise reduction filter to using a second noise reduction filter in a case that it is determined that the acoustic channel is in an interfered state based on the channel morphological parameter; and a noise reduction signal is generated by using the second noise reduction filter to cancel a noise signal received by the feedback noise reduction system. A frequency response of the second noise reduction filter in a predetermined frequency band is less than a frequency response of the first noise reduction filter in the predetermined frequency band.

Abstract: A virtual scene playback method is disclosed, which comprises: receiving a scene playback instruction and determining playback parameters according to the scene playback instruction, wherein the playback parameters include playback space and playback time; querying virtual space information and user model information corresponding to the playback parameters; and generating virtual scene playback content according to the virtual space information and the user model information. The present disclosure can save all the information in the virtual scene and play back the virtual scene corresponding to specific space and time. A virtual scene playback apparatus, an electronic device and a storage medium are also disclosed, which also have the above beneficial effects.
