Introduction: The Sound Environment Revolution for Healthy Living
Research by the World Health Organization shows that long-term exposure to noise levels above 55 dB increases the incidence of hypertension by 3%, and when windows are closed to block noise, indoor CO₂ concentrations can rise to over 1500 ppm (far exceeding the national standard limit of 800 ppm). Sanyuan Environmental Ventilation Soundproof Windows, with their synergistic "sound insulation + ventilation" technology, break the paradox of traditional doors and windows that "silence leads to oxygen deficiency, while ventilation leads to noise," redefining the standards for a healthy living acoustic environment.
Core Performance: Data Witnesses Technological Breakthrough
Technological Innovation: 3D System Solutions
1. Full-band noise interception system
• Acoustic shielding layer : Three-glass, two-cavity composite structure, which achieves a 92% noise blocking efficiency for mid-to-high frequency noise and reduces low-frequency vibration transmission loss by 60%.
• Labyrinth-style anechoic channel : Aerospace-grade microporous technology (pore size ≤ 0.2mm) combined with nano-gradient sound-absorbing materials achieves a sound insulation of over 35dB under ventilation conditions.
• Military-grade sealing system : EPDM composite foam strip + elastic sealant filling, eliminating sound transmission through gaps, reducing sound leakage around windows to below 8dB.
2. Durable materials and craftsmanship
• Thermally broken aluminum profiles : Multi-cavity structure filled with high-density polyurethane, corner joints are formed by injection molding process to create sealed cavities, improving sound insulation and thermal insulation performance.
• Damped soundproof glass : The sound insulation film is made of polyurethane elastomer, which can withstand environments down to -30℃ and improves the low-frequency resonance and high-frequency matching effect of insulated glass.
Scenario Validation: Benchmark Cases Demonstrate Strength
Case Study: Noise Reduction Project at a Railway Station in Lanzhou
Challenge : 24-hour railway operation noise reaches 110dB(A), with an indoor peak of 93dB(A), a project supervised by the Central Environmental Protection Inspection Team.
Solution : Custom-made ventilated and soundproof windows + low-frequency damping sound insulation felt.
Results: Meets the Class 3 sound functional zone standards, with daytime ≤65dB(A) and nighttime ≤55dB(A).
