Noise Reduction Comparison
Noise Reduction Percentages Can be Misleading
Noise reduction percentages can be misleading, and like statistics, can lie. The basic problem is the human ear. As the environment gets quieter, the ear becomes more sensitive to noise. This means that some of the noise reduction provided is lost.
- Soundproof Windows can reduce the current noise levels by 95% or by 75%, and both statements will be true: one is the instrument measurement, while the other is the perceived noise reduction. Additionally, depending on actual noise levels, the noise reduction may be perceived as 100%.
- Dual pane window sellers can say they stop the noise – and in some noise level environments they do. They can also say they reduce the noise more than 50% – true by instrument reading compared to a poorly sealing window.
It is very expensive to get a perceived noise reduction of anything beyond 20% with replacement windows. The maximum available perceived noise reduction still does not exceed 50%. These numbers will not solve a noise problem.
Soundproof Windows do significantly MORE and cost significantly LESS .

How Much Noise Reduction is Enough?
Our experience indicates that 75% noise reduction is sufficient in almost all cases. Our customers feel the noise reduction is very significant – and definitely enough to end the noise pollution. No more need to raise voices or adjust TV volumes to tune out the excess noise.
Now you can sleep late, enjoy solitude and reduce stress. In the rare events where the noise levels are really extreme or the sensitivity is very high, we can install one of our recording studio quality windows and absolutely stop the problem, reducing the perceived noise levels beyond 95%. This is very seldom necessary and often your walls are not good enough and will become the new source of the noise problem. Our consultants can help you determine your best solution.
