Loss of "directness", will inevitably affect the damage "the enjoyment of beauty" audience is one, the audience and the actor mingled, integrated, so that the audience has a special feeling.
Because of the special nature of the square dance performance form, the performance site on three or four sides are the audience, the performance stage and the audience as a whole, the performance site is crowded firestorm lively. This makes most of the square dance performance content must be enthusiastic and cheerful, with the dance terminology is "emotional dance".

Square dancing has become a headache problem, looking for a "you dance happy, I sleep peacefully" balance, seems to have become a city management on the Goldbach's conjecture, so that the emergence of a high-pitched guns, Tibetan mastiffs, throwing rats and other pernicious "crack" means. For square dance nuisance, some local cultural management and cultural team representatives, representatives of the public signed a convention on square cultural activities, from the venue, length, time, volume and other aspects of the square cultural activities to limit the violation of the team to education and punishment, the results are obvious.
The problem of square dancing should not be insoluble, why there is still chaos? When the law enforcement office "mobile" up, from decentralized law enforcement into joint law enforcement, the national regulations and local realities effectively combined, in the noise of the place, the public reported the place to cruise back and forth, floating sinking, law enforcement officers out of the office to actually arrive at the scene, so that the abstract legal provisions and public **** policy to open the eyes of law enforcement, supplemented by sincere persuasion and persuasion, and the public **** policy, and the public **** policy. Supplemented by sincere exhortation and persuasion, there will be a different effect. Active directional speakers
In 2014, the second session of the fair, Fudan University scientists said they had successfully invented a square dance noise "stopping artifact" - active directional speakers.
Ordinary loudspeakers emit sound in all directions, to realize the orientation, the diameter of the speaker must be made very large. Different from the principle of traditional speakers, active directional speakers first low-frequency sound signals contained in a highly directional high-frequency signals on top, and then amplified, launched into the air, and then the air will be the high-frequency signals quickly filtered, the audible sound signals on it will be naturally filtered out, to achieve the directional propagation of the laser like.
Active directional speakers are able to control sound waves in a specific area, in which the sound waves are very strong, and out of this area, the sound waves will be very weak, or even none. If square dancers use this kind of speaker to play music, its nuisance 'embarrassment' can be solved." Ma Jianmin said. In addition to the square dance noise as a "forced stop artifact", active directional speakers can also be used in advertising exhibitions, waiting rooms, bus stops and other scenarios, to achieve the sound of a specific group of people directional broadcasting.
