Why Noise Reduction Matters in Modern Homes
The nostalgic roar of an old train in a film may stir childhood memories, but when that same sound comes from outside your home every day, it quickly turns into an endless frustration. This is noise pollution.
Noise is more than just an annoyance that disturbs sleep – long-term exposure can cause irreversible damage to both physical and mental health. In fact, noise has become one of the most severe environmental pollutants of modern life.
That’s why sound insulation is no longer a luxury – it is an essential requirement for creating a calm and healthy living space.
What Is Noise and Why Is It Harmful?
Noise is any unwanted sound that causes discomfort, irritation, or disrupts communication, work, study, or rest.
Hearing range of the human ear: 20Hz–20kHz
Most sensitive range: 2kHz–5kHz
Comfortable volume: 0–40dB
Uncomfortable threshold: 60dB+
Risk of hearing loss: 120dB+ (even one minute can cause temporary deafness)
Types of Noise by Frequency
Low-frequency noise (20–500Hz): air conditioners, trains, airplanes, car engines, ships, washing machines, refrigerators.
Travels long distances, penetrates walls easily, causes the most harm.
Mid-frequency noise (500Hz–2kHz): elevators, traffic sounds.
High-frequency noise (2kHz–20kHz): horns, instruments, dogs barking, loudspeakers, conversations.
Weaken quickly over distance, easier to block.
Choosing the Right Soundproof Windows and Doors
When external conditions cannot be changed, upgrading to high-quality soundproof windows and doors is the smartest solution. A well-designed window can reduce outside noise by more than 30dB, and with the right configuration, even more.
Glass – The Core of Noise Reduction
The type of glass directly determines how effective your windows are at blocking noise.
For High-Frequency Noise – Double Glazing (Insulated Glass)
Double-glazed windows consist of two or more glass panes separated by an air or gas-filled cavity. This structure absorbs mid-to-high frequency vibrations, significantly reducing sound transmission.
Thicker glass = stronger insulation (every doubling of thickness reduces noise by 4.5–6dB).
Performance can be further improved with inert gas filling and wider gaps.
For Low-Frequency Noise – Laminated Glass
Laminated glass has a PVB interlayer that absorbs sound vibrations, especially effective against low-frequency noise where ordinary double glazing struggles.
The interlayer acts as a damping barrier.
However, extreme cold can reduce elasticity and weaken performance.
Best choice: laminated insulated glass (combines both technologies).
Frame and Sealing – Automotive-Grade Performance
Noise insulation is not just about glass – the frame and sealing structure play an equally critical role.
CIVRO uses EPDM automotive-grade sealing materials with excellent elasticity and rebound.
Multi-chamber sealing designs work together with the glass to build a complete soundproof barrier.
Opening Mechanism – Better with Casement Windows
While there are many window opening styles, casement windows outperform sliding windows in air-tightness, wind resistance, and sound insulation.
Inward tilt-and-turn windows: safer, softer ventilation, same insulation benefits as casement.
Top-hung windows: similar advantages with extra flexibility.
