A SIMPLE SOLUTION AGAINST NOISE: ACOUSTIC CURTAINS


How do soundproof curtains work?

Soundproof curtains aim to block and absob the noise.

  • Sound proofing (or sound insulation) attempts to stop noise by blocking the acoustic wave from traveling to adjacent spaces. Insulation can only be achieved with mass and/or multiple layers 
  • Sound absorption aims to reduce noise by limiting the reverberation of the sound wave within a space.,Absorption can be obtained with light materials (such as specific fabrics) that are applied to walls or windows.

To dampen noise the curtain has to be heavy, made up with multiple layers. But realistically, a curtain can't cut out all the noise... The curtain muffles the sound and the atmosphere is quieter. Therefore, even if you hear the noise, it's much less agressive. We have a lot of customer reviews stating that although people still hear some noise, they are no longer disturbed or woken up by it.

Sound frequencies get “trapped” in between the multiple fabric layers of the curtain. This prevents sound from going through the curtain, and for the frequencies that don't get blocked, the thick curtain will absorp the echo.

Based on our tests, the transmission of the sound wave is reduced  the reverberation is reduced: for a surface area of approximately 215 square feet, the reverberation time is reduced by 0.4 seconds.


Which soundproof curtain material is best?

There are various sound insulation materials available, but making a curtain that is not only sound blocking but also functional and decorative is the real challenge. We developed after years of testing the best combination of fabrics which we also hold a patent for (U.S. Patent No. 9,475, 260).

Every sound insulation curtain has to be heavy: the heavier the curtain, the better the sound insulation. Our challenge was to develop a heavy sound insulation curtain that would be suitable for the residential market. A curtain that can be hung with a regular curtain rod and brackets.

The Moondream Soundproof Curtain uses our own patented technology (U.S. Patent N° 9475260) with 3 layers of strategically assembled materials to obtain the best results in sound insulation that can be achieved with a fabric curtain. Our product has been tested by independant laboratories to confirm its perfomance.

  • Sound insulation: Noise reduced by four-fold, reaching a drop of up to 7 decibels (1). Reverberation of sound in the room reduced for a quieter atmosphere, e.g. for a surface area of approximately 215 ft² the reverberation time is reduced by 0.4 seconds (2).
  • Thermal insulation: Up to 37% reduction of heating costs in winter (3) and a drop in temperature during summer (4). 
  • Light insulation: 100% blackout effect for improved sleep quality.

 

What makes a good soundproof curtain?

An effective soundproof curtain has to be made with multiple layers of different fabrics, be quite thick and heavy. This means that lightweight sound blocking curtains are acoustically almost ineffective.

MOONDREAM soundproof curtains are made with 3 different layers and weigh between 4lbs to 7lbs depending on the length. They have been engineered to muffle the sound coming from the outside to create a more calm and comfortable interior. They also absorp the noise once it's inside the room.

In fact to cut out the noise, it's necessary to multiply the applications (rug etc..) 

The performance of our sound absorbing curtains has been tested and certified by independent laboratories.
