According to relevant laws and regulations, loud live broadcast in the square may be considered as disturbing the people, and whether it is disturbing the people needs to be judged according to local laws and regulations. Generally speaking, disturbing the people refers to acts that interfere with, hinder or destroy the normal life order and living environment of others. If the live sound in the square exceeds the urban noise limit standard and the normal living habits of residents, it may be considered as disturbing the people. However, the restrictions on sound size, time and frequency may be different in different regions, so it is best to refer to relevant local laws and regulations to determine whether it is illegal to disturb the people. If your specific region and laws and regulations, please consult the relevant government departments or legal professionals to get an accurate answer.
