Quiet Space Empowers Education | Professional Ventilation and Soundproof Windows Reshape the Campus Acoustic Environment

Noise control in educational spaces: a revolution concerning learning efficiency

Research by the World Health Organization shows that when classroom background noise exceeds 35 decibels, students' reading comprehension ability decreases by 4% and the error rate in arithmetic operations increases by 11% (WHO, 2018). Faced with multiple noise interferences from street traffic, playground activities, and corridor noise, the sound insulation deficiencies of traditional windows have become a hidden 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 should be ≥30dB, and ≥35dB for special locations such as language classrooms.

Sanyuan Ventilation and Soundproof Window: Campus Sound Environment System Solution

Core technology innovation

Three-element ventilation and soundproof window: measured sound insulation 35-50dB

The triple-glass, double-cavity composite structure-tempered glass + PVB interlayer + 12A argon gas hollow layer-achieves a 92% noise blocking efficiency for mid-to-high frequency noise (125-4000Hz).

Low-frequency damping technology: Built-in polymer damping material reduces transmission loss of low-frequency noise below 250Hz (such as vibrations from playground activities) by 60%.

Healthy ventilation system | Air exchange rate of 60-120 m³/h when windows are closed

German TÜV certified micro-positive pressure technology: 2 air exchanges per hour throughout the house, 99% PM2.5 filtration efficiency, and 99.97% H1N1 virus inactivation rate.

The Sanyuan ventilation and soundproof window received a scientific and technological achievement evaluation in 2019 (evaluation result: leading in China), and in 2021...

It was included in the National Advanced Pollution Prevention and Control Technology Directory of the Ministry of Ecology and Environment in 2018.

Energy optimization: Compared to traditional window ventilation, air conditioning reduces heat loss by 50% and achieves annual energy savings of over 30%.

Engineering-grade safety protection | Wind pressure resistance level 9

The thermally broken aluminum profile with a multi-cavity structure design has passed the highest level of testing in GB/T 7106-2019.

A typhoon season test conducted at a middle school in East China: No leakage or deformation was observed under an instantaneous wind speed of 23 m/s.

Empirical data: Making the value of quiet operation quantifiable

Improved focus: Ventilated and soundproof windows were installed in 36 classrooms at a key primary school in Shanghai, resulting in a 58% reduction in classroom disturbances (data tracked by the Education Evaluation Center of East China Normal University).

Air quality assurance: A winter test at an international school in Beijing showed CO₂ concentration consistently below 800 ppm, better than the ASHRAE standard.

Education is a silent force of growth; we protect every inch of this tranquil soil.
