Noise insulation of windows

Today, the best protection against external noise are plastic windows. Therefore, if you are determined to get rid of traffic noise and other external stimuli, then you should simply change your old windows to new ones.

In this case, it is necessary to seriously approach the choice of the double-glazed window itself, which is inserted into the plastic profile and performs a soundproofing function.

A wonderful option is a single-chamber double-glazed window. It consists of two glasses and copes with the protection of the room from extraneous noise.

But if you have a noisy track under the window, then this design may sometimes not be enough, so it will be advisable to install a two-chamber double-glazed window. This design already includes three glasses that are hermetically connected around the perimeter.

It is also possible to insert double-glazed windows with glass of various thicknesses: 4 mm + 4 mm + 6 mm, this gives an additional effect due to the partial elimination of resonance phenomena.

Recall that the volume of sound is expressed by sound pressure. At 0 dB – the lower threshold of sensitivity of the human ear is accepted. The noise level on a noisy street is 80 dB, 50 m from it – 75 dB. Windows reduce noise by another 35-45 dB, as a result of which a sound comfort level of 40-45 dB is maintained in your home (such noise forms tree leaves in light winds 🍂).
