1、 Case background

Whenever night falls and the lights come on, the park square becomes a stage for middle-aged women to release their vitality and enjoy life. Square dance, a unique cultural phenomenon that combines fitness and entertainment, quickly spread among middle-aged women with its cheerful melody and light movements, becoming a popular choice for them to exercise, enhance friendship, and enjoy the fun of life.

However, with the popularity and increasing number of fans of square dancing, the accompanying noise problem has become increasingly prominent. The high decibel music not only breaks the tranquility of the surrounding residential areas, but also seriously affects people's rest and sleep, causing conflicts and dissatisfaction among many neighbors. For a time, the noise of square dancing has become a stubborn problem in urban management. How to balance the fitness and entertainment needs of square dancing enthusiasts with the quiet living environment of surrounding residents has become an urgent problem that needs to be solved.

Faced with this challenge, Xinhu Street in Guangming District, Shenzhen, with a high sense of responsibility and foresight, organized a team to conduct in-depth market research and technical investigation, striving to find a solution that can meet the needs of square dance enthusiasts and effectively reduce noise disturbance to the public. After multiple comparisons and arguments, Xinhu Street ultimately choseClear hearing acousticsSmart Dance Stage System(Directional Sound Smart Square Dance System)This has opened up a new path for noise control in square dancing, with significant results.

　　IIPlan deployment

After on-site investigation and testing, as well as professional sound field simulation design, Xinhu Street has decided toJinmao Park, Loucun Garden, Xiyun Zhuo GardenThese three representative communities have taken the lead in addressing the root causes of noise pollution, resolving the conflict between citizens' fitness needs and the noise disturbance caused by square dancing, and returning peace to the people.

In the deployment process, Qingting Acoustics not only focuses on deployment plans and technical implementation, but also attaches importance to the actual feelings and feedback of residents. Through scientific and reasonable planning and implementation, it strives to truly solve the problem of noise disturbance from the source, making square dancing a positive force to promote community harmony and enhance neighborly friendship, rather than an annoying source of noise.

　　IIIcore strengths

The "beamforming" directional sound system used in the smart dance venue system (directional sound smart square dance system) is based onIndependent directional sound algorithm and technologyTo solve the problem of square dancing disturbing people as the key point, the comprehensive smart sports service facilities integrating multiple functions such as "cultural publicity", "community service", "mass fitness guidance", "popular science publicity", and "grassroots convenience service" are built by using big data and Internet plus.

The smart dance venue system, as part of the "Suzhou Experience," was selected for the "2020 China Environmental Noise Pollution Prevention and Control Report." The beamforming directional speaker system used in the system was included in the "National Advanced Pollution Prevention and Control Technology Catalog," and the "Smart Dance Venue that Does Not Disturb the People" was included in the "2022 Sports Typical Case List

The system is transformed from multiple independent scientific and technological achievements in Qingting Acoustics, integrating leading directional sound technology and digital guided environmentally friendly speaker arrays. It achieves that the sound emitted by the equipment is concentrated in a fixed area for propagation, and after exceeding the range, the sound is greatly attenuated to below environmentally friendly decibels.

01 Environmental protection and noise reduction without disturbing the public. Leading the way with directional sound technology, it achieves precise directional transmission of sound and effectively solves the problem of noise disturbance to the public;

02 Sports and Tourism Promotion Complex is equipped with outdoor multifunctional display screens, integrating community security, cultural and legal publicity, and other functions into one;

03 Cloud based intelligent management can easily manage devices and venues through backend management systems and WeChat mini programs, achieving standardized management.

Through the backend and supporting mini programs, standardized management of equipment and venues can be achieved, and the need for multiple dance teams to play music simultaneously without interfering with each other can be met. This solves the problem of noise disturbance caused by cultural and sports activities from the source, optimizes the public sound environment, and promotes the harmonious integration of living environment and entertainment fitness.

　　4effect evaluation

Since the introduction of the Clear Listening Acoustic Smart Dance System (Directional Sound Smart Square Dance System), the noise problem of square dance in Xinhu Street has been significantly improved, and the overall effect is good. Residents have reported that in the past, multiple dance teams were active at the same time, and each group was relatively close to each other. In order to avoid interference with each other, every sound system was turned on at a high level, and the noise was basically above 70 decibels. Now it's much better, not only has the noise decreased, but we (dance teams) also play different songs before each other and won't 'fight' anymore. This change not only improves the quality of life of residents, but also promotes the harmonious development of community culture, truly realizing the beautiful vision of 'civilized dancing, shared harmony'. In the future, Xinhu Street may work together with Qingting Acoustics to gradually expand the deployment scope of the smart dance venue system (directional sound smart square dance system), improve the public sound environment, and further promote the construction of ecological civilization
