When talking about sound absorbing curtains in my roundup review, one of the point being bought forward is that most of the curtains are rather heavy. This is not a coincidence. It has been shown that a heavy curtain can reduce noise levels as much as 3 times when compared to a regular curtain. So, the next time you are thinking about using curtain to reduce noise for a better night’s sleep, think heavy.
Types of heavy curtains
Due to the materials used and the ways they are made, some curtains are heavier than others. Below is what you should be doing for when shopping:
- Length: This is the easiest one to get right. The longer the curtain, the heavier it will be and has a bigger area for sound absorbing. There is also another benefit of getting longer curtains. They can completely block the windows which are one source of noise. If you got a bigger sound absorbing curtain covering the window, it has more surface area to absorb the sound.
- Thermal insulating: Curtains with thermal insulating capabilities are thicker in natures and hence heavier. The additional thickness is needed to ensure the curtains are able to block out the heat and keep the house cool. This is why many of the thermal curtains are, by default, good sound absorbing curtains as well. The same reasons is also why blackout curtains are another nice option if you want heavy curtains.
- Material: Certain materials are heavier by construction. Suede and velvet are two of the heaviest curtain material around, which is why they are the best curtains for soundproofing. When you combine suede or velvet material with a long length, it will achieve the best results.
Pleated curtains help as well
Besides being heavy, another way curtains can be soundproofing in the number of pleats they have. There are a couple of ways pleated curtains can improve noise canceling or sound absorbing:
- Thickness: A pleated curtain is thicker due to the number of new layers created by the pleats. If nothing else, thickness will help to reduce noise coming in.
- Heavy: Pleated curtains are also more heavy as more materials are used.
- Pockets of air: Pleated curtains can trap some air between the pleats which act as additional barriers for the sound to penetrate through. The effect is like that of an insulated glass panel except the effect is much much weaker. If you want to know more this effect, read this article on the best windows for noise reduction.
If you want a heavy curtain for soundproofing, choose one that is longer, has thermal insulating capabilities and made of suede and velvet. You should get a longer piece because you can form pleats that will further enhance the sound absorbing ability of the curtains.
