Introducing our example of using sound-absorbing materials at the Foshan Nanhai District Jiamei Experimental School, located near the scenic West Lake district of Hangzhou, adjacent to Guangzhou, and spanning across Foshan. As a member of the Shimen Education Group, the Foshan Nanhai District Jiamei Experimental School embraces the innovative "Jiamei Education" philosophy, centered around the core idea of "Embracing Fusion and Beauty Together."
Following the national standards for sound insulation design in civil buildings, amplification system design for halls, and acoustic design and measurement guidelines for sports arenas, we conducted specialized acoustic decoration for the venue to avoid issues like echo and sound focus, ensuring an optimal audio experience.
In the case of the multi-functional hall, we adhered to the provisions of the "Acoustic Design of Theater, Cinema, and Multi-Purpose Hall Buildings" (GBT50356-2005). With an effective volume of approximately 2250m3, we aimed for a mid-frequency reverberation time of T≤0.9±0.10s, suitable for academic presentations, small to medium-sized meetings, and artistic performances. To facilitate real-time monitoring and program switching on stage, we suggested adding a control room behind the audience seats, reducing the seat count by 17 to accommodate approximately 473 people. The hall's design concept revolved around themes like "Vibrant Youth," "Fertile Ground for Growth," "Sweat and Flourish," and "Vitality and Pursuit of the Future." We used wood patterns to represent sunshine, vitality, and a youthful spirit, with a yellow background and green accents to create an atmosphere of energy, teamwork, and enthusiasm. The arrangement of rectangular wooden slats added a sense of vigor, effectively conveying the positive and sunny attitude of contemporary youth. We used acoustic panels with crystal sand texture for the wall, double-layer gypsum boards for the ceiling, PVC plastic flooring for the audience area, and special stage flooring for the stage, along with dedicated auditorium seating.
For the sports arena's acoustic design, we considered the critical technical indicator of reverberation time. With an effective volume of approximately 11,000m3, we targeted a mid-frequency reverberation time of T≤1.4±0.10s, in accordance with the "Acoustic Design and Measurement Guidelines for Sports Venues" (JGJ/T131－2012). The design focused on meeting the acoustic requirements for student basketball and badminton training and competitions. The acoustic decoration and audio system were designed to cater to these specific functions. As the multi-functional hall already served as a venue for meetings, we transformed the sports arena's stage area into a table tennis zone, catering to various ball sports. To address issues like echo and multiple reflections in the arena, we effectively controlled the mid-frequency reverberation time to achieve 1.4s±0.1s. For this purpose, we used red glass fiber slotted sound-absorbing structures for the walls, full-frequency spatial sound-absorbing bodies for the ceiling, and PVC plastic flooring for the ground.
Our comprehensive acoustic design and application of sound-absorbing materials have resulted in optimal sound environments for both the multi-functional hall and sports arena at the Foshan Nanhai District Jiamei Experimental School, ensuring clear and uniform audio distribution and enhancing the overall experience for students and audiences alike.
