Intelligent audio control system and method

Abstract

The invention discloses an intelligent audio control system and method, and the method comprises the steps that the partitioning of a meeting place is carried out according to the distribution of pickup devices, so that each region comprises a pickup device and a corresponding sound amplification device which is closest to the pickup device; an intelligent identification module is connected with the pickup device in each region of the meeting place to detect the starting state of the pickup device in each region so as to obtain a corresponding identification signal; a region control module is connected with the intelligent identification module and the sound amplification device in each region of the meeting place, so that the volume of the sound amplification device in each region is adjusted according to the identification signal; when the volume of the sound amplification device is adjusted and when the pickup device in a certain subarea is detected to be started, the volume of the sound amplification device corresponding to the region is turned down by a set amplitude, and the volumes of the sound amplification device in other regions are turned up by the set amplitude, so that the problem that when the pickup device is started, the sound emitted by the corresponding sound amplification device is picked up by the pickup device to form closed-loop self-excitation and generate howling is avoided.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an intelligent audio control system and method. Background technique [0002] As the sensitivity of modern microphones is getting higher and higher, it is becoming more and more difficult to control the sound self-excited howling produced by the microphone in multi-functional places such as conference rooms. The sound howling problem is caused by the sound from the speaker being picked up by the microphone to form a closed-loop self-excitation. At present, the main method to deal with this problem is to suppress the sound frequency point that is easy to form self-excited feedback in the sound field or to lower the sound reinforcement volume of the whole field. The method of suppressing the sound frequency point that is easy to form self-excited feedback in the sound field will affect the sound quality of the sound, and the solution of reducing the sound reinforcement volume of...
