In the process of promoting educational modernization, the comprehensive improvement of campus acoustic environment has become a key link in building high-quality educational spaces. In August of this year,Qingting Acoustics is concentrated in Tianjin, consisting of three newly built schools, Huishengdao Nine Year Integrated School, Xiqing District Sixth Kindergarten, all of which were put into use in September this yearTianjin Experimental Primary School Xiqing SchoolCreated a demonstration case of healthy sound stateAmong them, Tianjin Experimental Primary School Xiqing School synchronously deployed a quiet playground system (playground mute system) and a classroom balanced sound field system (integrated classroom speaker); Huishengdao nine-year integrated school and Xiqing District Sixth Kindergarten focus on installing a quiet playground system (playground mute system), aiming to control noise from the source and achieve harmonious coexistence between the campus and the community.

Huishengdao nine-year integrated school, Xiqing District Sixth Kindergarten, and Tianjin Experimental Primary School Xiqing School are all newly built schools located around densely populated residential areas with prominent demands for sound environment management. Huishengdao nine-year integrated school is adjacent to multiple residential communities around the sixth kindergarten in Xiqing District. Tianjin Experimental Primary School Xiqing School is located to the west of Greentown Xiangli Nanyuan and Xiangli Beiyuan, and to the east is a newly built residential community such as Dongfang Jiuxi. In order to avoid potential noise disturbance after the school is built, the education department attaches great importance to the construction of the campus acoustic environment. Acoustic management has been included in the overall planning of the campus environment since the early planning stage, and is committed to creating a quiet and comfortable teaching and activity space.

　　Forward planning with precise implementation

In order to achieve the management goal of "harmony from the starting point", the school has included sound environment management as a key planning focus in the preparation stage of school construction, and carried out multidimensional and multi-level research and evaluation work. The education department specially organized a team to go to Chilong Middle School, which has already implemented the same plan, for on-site experience, to deeply understand the actual operation effect and application value of the quiet playground system (playground mute system). After comprehensively comparing multiple technical solutions and completing multiple on-site inspections, the school finallyChoose the independently developed Clear Listening AcousticsQuiet playground system(Playground Silence System)）andClassroom Balanced Sound Field System(Integrated Classroom Speaker).

The Qingting Acoustics R&D team actively responds to the needs of various schools,Going deep into the campus multiple timesOn site, with the school management team, physical education teachers, and representatives from the surrounding communityConduct in-depth discussions，Comprehensive investigationBased on the usage characteristics, sound environment distribution, and community noise sensitive areas of playgrounds at different time periods, and the usage scenarios and audience characteristics of different types of schools (such as primary schools, nine-year integrated schools, and kindergartens), the team relies onActual acoustic measurementData and specific requirements for the systemCustomized debugging and deploymentTo ensure its optimal adaptability in different campus environments and assist the school in achieving its goal of building an acoustic friendly campus from the early stages of operation.

　　Surrounding community residents

We were a bit worried during the construction of the school, after all, we were so close that we were afraid the sound of the playground broadcast would affect our rest. However, surprisingly, since the start of the school in September, we have hardly heard the broadcast sound inside the school. Even the long-term use of the sound system during the opening ceremony and the concentrated activity period during the daily break have not been affected. The school has considered it carefully, and we residents are also very comfortable

　　Customized solution technology protection

Clear Listening Acoustics provides a comprehensive solution for the construction of a smart sound state system that combines internal and external education on campusExternally,Quiet playground system(Playground Silence System)By adopting advanced directional sound technology and precisely controlling the propagation direction and range of sound waves, the sound of playground broadcasts, sports music, and other sounds can be efficiently collected within the venue,Suppress noise overflow from the source，Significantly reduce interference with surrounding communitiesTo achieve the goal of 'returning peace to the people and sound to the school';domestically,Classroom Balanced Sound Field System(Integrated Classroom Speaker)Focus on improving the uniformity and clarity of the indoor teaching sound field to ensureEvery student can hear the teaching content clearly，Protecting students' hearing healthAnd effectively reduce the burden of teachers' voices, creating a healthy and intelligent teaching environment. The two major systems work together to enhance the overall acoustic performance from outdoor to indoor, from noise reduction to quality improvement, laying a solid foundation for the construction of a modern campus acoustic environment.

　　Clear Listening AcousticsQuiet playground system（Playground Silence System）Has been awarded the title of "Little Giant" in the field of sports, specializing in excellence and innovation, and together with the classroom balanced sound field system (integrated classroom speakers), they form a comprehensive solution for campus acoustic environment covering indoor and outdoor scenes. At present, these two systems have been applied in more than 5000 schools in more than 50 provinces and cities across the country, fully verifying the progressiveness of listening acoustics technology and scene adaptability.

From the synchronous implementation of three newly built schools in Tianjin to the extensive verification of more than one campus across the country, Qingting Acoustics has reshaped the standards for campus sound construction with innovative acoustic technology. It not only provides schools with a systematic solution of "outdoor noise reduction and indoor clarity", but also strives to build a new sound state of harmonious coexistence between campuses and communities. In the future, Qingting Acoustics will continue to deepen its innovation and application in acoustics, and promote "harmonious sound state" as a standard for modern urban construction with smarter and more standardized sound environment solutions, contributing professional strength to building a livable and conducive to learning sustainable development environment.
