Noise Control in Educational Spaces: A Revolution for Learning Efficiency
A World Health Organization study shows that when classroom background noise exceeds 35 decibels, students' reading comprehension ability decreases by 4% and their arithmetic error rate increases by 11% (WHO, 2018). Faced with multiple noise disturbances such as street traffic, playground activities, and hallway noise, the sound insulation defects of traditional windows have become an invisible weakness affecting teaching quality. The Ministry of Housing and Urban-Rural Development's "Code for Sound Insulation Design of Civil Buildings" (GB 50118-2010) clearly stipulates that the airborne sound insulation of exterior windows in school buildings must be ≥30dB, and in special areas such as language classrooms, it must be ≥35dB.
Three-dimensional ventilation sound insulation window: campus sound environment system solution
Core technology innovation
Three-dimensional ventilation soundproof window: measured sound insulation 35-50dB
Three-glass two-cavity composite structure: tempered glass + PVB interlayer + 12A argon hollow layer, with a blocking efficiency of 92% for medium and high frequency noise (125-4000Hz)
Low-frequency damping technology: Built-in polymer shock-absorbing material, the transmission loss of low-frequency noise below 250Hz (such as playground activity vibration) is increased by 60%.
Healthy ventilation system | Closed window ventilation volume 60-120m³/h
German TÜV certified micro-positive pressure technology: 2 air changes per hour, 99% PM2.5 filtration efficiency, 99.97% H1N1 virus inactivation rate
Sanyuan ventilation sound insulation window obtained scientific and technological achievement evaluation in 2019 (evaluation result: domestic leading),
It was selected into the National Advanced Pollution Control Technology List of the Ministry of Ecology and Environment.
Energy consumption optimization: Compared with traditional window ventilation, air conditioning heat loss is reduced by 50%, and the annual energy saving rate exceeds 30%.
Engineering-grade safety protection | Wind pressure resistance level 9
Thermal break aluminum profile + multi-cavity structure design, passed the highest level test of GB/T 7106-2019
Typhoon season measurement at a middle school in East China: No leakage or deformation at an instantaneous wind speed of 23m/s
Empirical data: making the value of silence quantifiable
Improved concentration: A key primary school in Shanghai installed ventilated and soundproof windows in 36 classrooms, reducing classroom disruptions by 58% (tracking data from the Education Evaluation Center of East China Normal University)
Air quality assurance: Winter measurements at an international school in Beijing show CO₂ concentrations consistently below 800 ppm, exceeding ASHRAE standards.
Education is the power of silent growth. We protect every inch of quiet soil.
