90% of noise in urban residences enters through windows: Sanyuan Environmental Soundproof Window Solution

Did you know that 90% of external noise intrudes into urban residences through windows? This conclusion is not alarmist; it's core data confirmed by authoritative media outlets such as Upstream News and CNR.cn in conjunction with acoustic research institutions. For bustling urban areas, the "Residential Project Code" GB 55038-2025 stipulates that the weighted sound insulation (CRw + Ctr) of exterior doors and windows facing main traffic arteries in residential buildings should not be less than 35 dB ; the weighted sound insulation (CRw + Ctr) of other exterior doors and windows should not be less than 30 dB . Long-term exposure not only affects sleep quality but also increases the incidence of hypertension by 3% (World Health Organization research) and reduces children's cognitive abilities by 23% (Tongji University follow-up data). As a leading company in sound environment management, Sanyuan Environment, with its core technology of ventilated soundproof windows , builds a "silent defense line" for millions of families.

The "invisible channels" for noise intrusion: Why are windows a weak point?

The sound insulation capabilities of ordinary residential windows are generally insufficient: single-pane windows and traditional double-glazed windows are unable to block 85 decibels of traffic noise or 110 decibels of rail traffic. Even more easily overlooked is that "acoustic loopholes" such as window gaps and drainage holes can drastically reduce noise reduction effectiveness-actual tests show that unsealed window sill drainage holes can cause a loss of 8 decibels in sound insulation. Furthermore, the glass alone cannot determine the sound insulation of a window; five major factors must be considered simultaneously: the window frame, glass thickness, hardware configuration, manufacturing process, and installation method !

Sanyuan Environmental Solutions: More Than Just Sound Insulation, It Understands the Tranquility of "Breathing"

The Sanyuan ventilation and soundproof window integrates acoustic engineering and aerodynamic innovation, achieving the dual value of "sound insulation + ventilation" through a "three-layer protection system":

• Acoustic shielding layer : Adopting a three-glass, two-cavity composite structure, it achieves a 92% blocking efficiency for mid-to-high frequency noise (such as human voices and horn sounds) and a 60% reduction in transmission loss for low-frequency vibration noise (such as truck roar).

• Intelligent ventilation layer : Built-in labyrinthine sound-absorbing channel, the air exchange rate reaches 60-120m³/h when the window is closed (equivalent to 2 air exchanges in the whole house per hour), and the PM2.5 filtration efficiency is 99%, solving the pain points of traditional soundproof windows: "suffocating when the window is closed and noisy when the window is open";

• Sealing and protective layer : Multiple EPDM sealing strips + elastic sealant filling eliminate sound transmission through gaps. Actual tests show that sound leakage around the window can be reduced to below 8 decibels after installation.

Case Study: From Noise-Rich Area to Quiet Showroom

Case 1: Renovation of a residential community near a highway in Chengdu

Before renovation : Located 40 meters from the Chengming Expressway, indoor noise reached 54 decibels when windows were closed (14 decibels exceeding the standard), and the resident complaint rate exceeded 80%.

• Solution : Install a three-element ventilation and soundproof window;

• Results : Indoor noise was reduced to 35 decibels (meeting national standards), 80% of residents reported "sleeping through the night with windows closed for the first time", and the number of complaints dropped to zero.

Case 2: Noise Reduction Project at Lanzhou Railway Marshalling Yard

• Pain point : Located next to a railway marshalling yard, the indoor noise peak reaches 93 decibels, and it has been listed as a project under the supervision of the central environmental protection inspection.

• Technological breakthrough : Adopting a composite solution of low-frequency damping sound insulation felt and laminated insulated glass;

• Results : Noise reduction reached 58 decibels, indoor noise was stably controlled below 35 decibels, passed environmental protection acceptance and obtained "National Advanced Pollution Prevention Technology" certification.

Choose Sanyuan Environment: Protecting Your Sound Quality with Professional Technology

The "Residential Project Standard" implemented in 2025 has raised the wall sound insulation requirement from 45 decibels to 50 decibels. Windows, as the "main channel" for noise intrusion, directly determine the quality of living due to their sound insulation performance. Sanyuan Environment, a national high-tech enterprise , possesses nearly 100 acoustic patents, and its ventilated soundproof windows have been included in the National Advanced Pollution Prevention and Control Technology Directory of the Ministry of Ecology and Environment.

Say goodbye to noise pollution, starting with a professional soundproof window . Sanyuan Environment provides a full-process service from "noise testing - customized solutions - factory production - dust-free installation - regular maintenance," allowing every family to rediscover a deep tranquility of 30 decibels in the bustling city.
