Introduction: Sound Environment Revolution for Healthy Living
A World Health Organization study shows that long-term exposure to noise levels above 55dB increases the incidence of hypertension by 3%. When windows are closed to block out noise, indoor CO₂ concentrations can rise to over 1500ppm (far exceeding the national limit of 800ppm). Sanyuan Environmental Ventilated Soundproof Windows utilize a synergistic "soundproofing + ventilation" technology to overcome the paradox of traditional doors and windows: "silent windows lead to oxygen deprivation, while ventilated windows lead to noise," redefining the standard for a healthy living sound environment.
Core performance: Data witnesses technological breakthroughs
Technological innovation: 3D system solutions
1. Full-band noise blocking system
• Acoustic protection layer : three-glass two-cavity composite structure, with a blocking efficiency of 92% for medium and high frequency noise, and a 60% reduction in low-frequency vibration transmission loss.
• Labyrinth-type sound-absorbing channel : aerospace-grade microporous technology (aperture ≤ 0.2mm) combined with nano-gradient sound-absorbing materials to achieve a sound insulation of more than 35dB in ventilation state.
• Military-grade sealing system : EPDM composite foam strips + elastic sealant filling to eliminate sound transmission through gaps, reducing window leakage to below 8dB.
2. Long-lasting and durable material technology
• Broken bridge aluminum profile : The multi-cavity structure is filled with high-density polyurethane, and the corners are assembled using a glue injection process to form a closed cavity, thereby improving sound insulation and thermal insulation performance.
• Damping soundproof glass : The sound insulation membrane is made of polyurethane elastomer, which can withstand an environment of -30℃ and improve the low-frequency resonance and high-frequency matching effect of insulating glass.
Scenario Verification: Benchmark Cases Testify Our Strength
Case: 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), and is a central environmental protection inspection and supervision project.
Solution : Customized ventilation sound insulation windows + low-frequency damping sound insulation felt.
Effect: Meets the standards for Class 3 sound functional areas, ≤65dB(A) during the day and ≤55dB(A) at night.
B-side value: co-building a new ecosystem for sound environment governance
Providing integrated "consulting-design-production-installation" services, saving 30% energy compared to traditional solutions.
Authoritative endorsement: technical strength builds trust
• Qualification certification : National specialized and innovative “little giant” enterprise (2022).
• Technological accumulation : Jointly developed with the Chinese Academy of Sciences, it has more than 100 national patents, and its ventilation and sound insulation window technology has been selected into the "List of Advanced Pollution Control Technologies" (2021) of the Ministry of Ecology and Environment.
Conclusion: Let technology return to the essence of human habitation
Sanyuan Environment (stock code: 833347), a full-industry chain provider of acoustic environment management services, is redefining the standard of healthy living with nearly 20 years of technological expertise.
