How much noise can be reduced by soundproof curtains?

STC Ratings?

A common question is how much noise can actually be reduced by soundproof curtains. Before we can answer this however we must look at a term used to rate soundproofing materials like curtains, drywall, and windows. STC or also known as Sound Transmission Class is a rating of how well airborne sound is eliminated by the object in question. In other words, it can approximately tell you how much decibel reduction in noise you will get. We’re going to dive into a bit more detail than we normally would in this post so just be warned it may not make as much sense the first time through.


Quick decibel levels comparison

20dB – Watch Ticking

30dB – Whisper

60dB – Normal Conversation

70dB – Busy Street

90dB – Lawn mower


Drywall, windows, and noises

While in your house a typical layer of drywall with no insulation you’re looking around an STC of 30. This is also known as a paper thin walls because a person on the other side of the wall can hear you talking. So take a normal conversation decibel level of 60dB minus STC of 30 which you’re left with 30dB. Note that different frequencies can affect how much noise is actually reduced. As for windows a single-pane glass window will have an STC of between 20-25 which is doesn’t provide as much sound reduction as one would hope.


Soundproof curtains

The top of the line industrial strength soundproof curtains can have a STC rating of up to 35. Unless you’re looking to really stop the noise and spend the money you unfortunately will have to settle for living room curtains which won’t provide as great of an STC rating. A really good set of curtains will probably have a STC rating of up to 15 while you’re most likely going to get between 5-10. Now this may not seem a lot at first but your perception of increases or decreases in decibel levels can weigh in on how much noise is actually being reduced. Plus of course the more layers of noise reduction materials you setup between you and the problem the decibel levels can only go down.

Looking at a quick example of a noisy street, having 70dB can be reduced on average by 20 by a window and then again by 10 by curtains. You’ve reduced the noise down to almost a whisper which is more enjoyable to sleep to though you can reduce it even more with foam, double-pane windows, and an additional set of curtains.

  • Blackout – While stated as blackout, these do let some light in during the day but not too bad.

What to avoid in soundproof curtain selection

The number one mistake in curtain selection is based on price. Just because it’s high priced or says it has good quality doesn’t really mean much. Getting a really pricey set of curtains that look nice may end up to be almost as thin as a piece of paper. This doesn’t block out any sound what so ever and now you may have a several hundred dollar set of curtains that might as well be taken down the second you put them up if you actually wish to block out some noise. Not to also mention that thin curtains usually don’t block out any sun or moonlight which if they did could lower your heating and cooling costs.

Here are some quick general tips on what to avoid if you are looking for curtains to help keep the noise low:

  1. One type of material to avoid and while it maybe obvious is silk. Most of the time anything that deals with silk is going to be very light and not what you are looking for even though silk curtains do look nice.
  2. Any kind of curtain or drape that doesn’t block out the entire window. You will want at least 4 to 6 inches below the window sill covered.
  3. Watch out for curtains that have huge openings near the curtain rod. Some of these can be ignored if the curtain rod is placed high enough or covered with a valance, however a curtain that has no holes lets in a lot less sound.
  4. Curtains that allow sunlight through them even if a little bit. If light is able to get through that means sound easily can too which is why blackout curtains work so well.
  5. The word thin.


Just remember when you are making a selection to think about how can the sound get in and where the sound is coming from. If there is a hole anywhere the sound will find its way through.
