Do Blackout Curtains Block Noise? Are They Soundproof?

If your early morning sleep is getting ruined by noises from loud neighbors and unwanted sunlight on your face, you might want to get some heavy curtains.

A blackout curtain can be a solution to your problems. Now the question is, are blackout curtains soundproof? Let’s find out.

Are blackout curtains soundproof?

Blackout curtains are partially soundproof. They can block some sound but not much. Due to their heavy build, they usually block some sound. But this is not significant enough to call it a soundproof curtain. However, as they block some sounds, we can say it is partially soundproof.

Do blackout curtains block out or reduce noise?

Blackout curtains are an excellent option for your morning sleep. They can block sunlight and cut it off by around 90%. Although their primary goal is to block light, they can also block out sound to some extent.

Blackout curtains are made of heavy fabrics and are usually very thick. As a result, they absorb sound and block them. However, they will not soundproof your room completely.

To soundproof your room completely, you will need proper soundproofing curtains. But, heavy blackout curtains could be a good choice if you are low on budget.

Are all blackout curtains noise reducing?

No, not all blackout curtains are noise-reducing curtains. But, most of the manufacturers market their blackout curtains as noise-reducing curtains. It, however, is not true.

Due to the heavy nature of the blackout curtains, they sometimes dampen the sound. But in most cases, these curtains are not effective in reducing sound. However, some high-quality blackout curtains function as both.

So, if you are looking for a curtain that can prevent both sunlight and outside noise, you can invest in some good-quality blackout curtains. But to fully soundproof your room, you will need curtains that specialize in soundproofing.
