A sound control method and system for a conference room based on a sound insulation wall

Abstract

The present invention relates to a method and system for sound control in a meeting room based on a soundproof wall, which obtains the thickness distribution map of the soundproof wall in the meeting room, collects the meeting sound in real time, and calculates the actual sound insulation volume at each position of the soundproof wall; calculates the real-time sound amplitude at each position of the soundproof wall distribution; determine the first sound adjustment scheme set based on the actual sound insulation volume and sound amplitude distribution of each position; calculate the sound amplitude set at the preset position in the meeting room corresponding to the first sound adjustment scheme set, and adjust from the first sound amplitude set based on the sound amplitude set The solution focuses on determining the optimal sound adjustment solution, which improves the accuracy of sound insulation. The optimal sound control solution is obtained through double screening, only changing the volume of a few audio devices, while taking into account the sound insulation effect and the auditory experience of the participants.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a sound control method and system for a conference room based on a sound insulation wall. Background technique [0002] In today's increasingly competitive society, the number of meetings and the amount of meeting information are constantly increasing. In order to meet the needs of communication, meetings are indispensable in daily work. Meetings are a very important part of daily work. During the meeting, the use of audio equipment is unavoidable. However, the meeting room is usually set up adjacent to the office area. When audio equipment is used in the meeting room, sound leakage will inevitably occur. On the one hand, the confidentiality of the meeting content is reduced. On the other hand, it interferes with the work of other personnel.

Problems solved by technology

During the meeting, the use of audio equipment is unavoidable. However, the meeting room is usually set up adjacent to the office area. When audio equipment is used in the meeting room, sound leakage will inevitably occur. On the one hand, the confidentiality of the meeting content is reduced. On the other hand, it interferes with the work of other personnel

[0003] In order to avoid sound leakage, participants usually need to adjust the volume of all audio devices or individual audio devices by themselves, which is prone to untimely adjustments and inappropriate adjustments, and the accuracy of manual adjustments is low. Whether the sound insulation effect after volume adjustment The ability to improve can only be estimated by experience, and whether the participants can hear clearly after the volume is adjusted can only rely on hearing to feel whether the volume is appropriate, and the auditory experience of the participants is poor

The entire sound adjustment process cannot quantitatively calculate the sound insulation effect and auditory experience, the accuracy of the sound adjustment is poor, the adjustment process is complicated, and it is impossible to take into account the sound insulation and the participants' feelings at the same time

[0004] In addition, when adjusting the audio equipment, in the prior art, the method of reducing the volume of all audio equipment at the same time and at the same range is usually adopted, and the sound adjustment range is relatively large, ignoring the auditory experience of the conference room users, especially in large conferences, resulting in Participants cannot hear the meeting content clearly due to the low volume

The sound adjustment method is single and the accuracy is poor, and it is impossible to take into account the sound insulation and the experience of the participants at the same time
