Recent studies published in “Environmental Health Perspectives” indicate that noise levels at night may also increase the risk of heart attack by chronically elevating stress-related hormone levels. It's clear that noise adversely reduces people's health and quality of life.
Environmental noise is one of the major causes of disturbed sleep. Uninterrupted sleep is critical for proper physical and mental functioning in healthy individuals.
Apart from various effects on sleep itself, noise during sleep causes increased blood pressure, increased heart rate, narrowing of the blood vessels, changes in respiration, cardiac arrhythmias, and increased body movement.
Secondary effects measured the following day include fatigue, depressed mood and well-being, and decreased performance. People who sleep in a noisy environment have a shallower and less restful depth of sleep. This creates more health stresses on the body.
Most homes are built to protect against heat and cold. Often, they are not effective in blocking out noise. Studies of hundreds of offices and homes show that the most significant amount of noise comes through windows, not walls. While many people spend thousands of dollars on "sound proofing" the walls of their buildings, laboratory studies show that more than 90 percent of all the exterior noise comes in through doors and windows. Walls are almost never the problem.
Dual pane windows have been shown to be ineffective at handling noise issues. They are designed to handle heat and cold. The engineering needed for sound is quite different than for handling temperature. That's why people looking for noise relief who simply replace their dual pane windows are often disappointed.
A solution that has shown to reduce noise levels by 75-95 percent is adding soundproof windows. These are add-on windows which install quickly on the interior of a room. They blend with the window frame and dramatically reduce the level of outside noise that comes into the room. The technology behind these specifically engineered windows is grounded in engineering sound-eliminating window systems for recording studios.
Independent laboratory tests confirm noise reductions of 92-99 percent, as verified by audio instrumentation. While the human ear cannot detect that level of precision, the difference in noise levels in a room is significant.
If you live in a major city or on an otherwise noisy block, soundproofing your windows may just be the solution you need for uninterrupted sleep.
