Abstract

An embodiment of the application discloses a howlround preventive method and device, electronic equipment and a storage medium. The method includes: monitoring whether a target sound loop is present between first electronic equipment and second electronic equipment; if yes, determining whether howlround is present in the first and second electronic equipment according to the target sound loop anda sound signal received by the first electronic equipment; if yes, processing the sound signal in a preset howlround inhibition mode. By monitoring the target sound loop between the first electronic equipment and the second electronic equipment and the sound signal received by the second electronic equipment, it is possible to timely detect the howlround present in the first electronic equipment or the second electronic equipment; therefore, the howlround can be inhibited before worsening; the whole process has no need for cutting off sound input data, and howlround can be effectively prevented.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method, device, electronic equipment and storage medium for preventing howling. Background technique [0002] In daily life, when the distance between the microphone and the speaker is too close, howling and harsh sound will occur, seriously affecting the user experience. [0003] At present, most of the existing howling detection and suppression algorithms are energy detection of howling frequency points, that is, after detecting that the ability of a certain frequency point continues to be too strong, it is considered that howling occurs, and then the howling is suppressed by truncating the sound input data. Call. However, this way of suppressing the howling will cause the sound played by the speaker to appear intermittent, and the howling will still appear repeatedly, which cannot effectively prevent the occurrence of howling.
