Why do square dancers like to play it loud. Can't they hear themselves? The purpose is to be heard by others?

One study says that most square dancers were born around the time of the Cultural Revolution, and were influenced by various "movements" when they were young, so they preferred group activities! So some people think that square dancing is actually a kind of Cultural Revolution residual poison! And put the sound loud, just can create a lively atmosphere! As for the disregard for other people's feelings can be said to be a performance of poor quality! Now some provinces and regions have begun to legislate to control and reduce the impact of square dancing on the lives of people around!
