The best way to explain how soundproof curtains work is to term them misnomer. It means that they do not soundproof noise entirely. Therefore, don’t get surprised when you still hear sounds after installing your soundproof curtain.

Soundproof curtains work by capturing and absorbing a large amount of the sound coming into the room. As a result, less noise gets into your space. It, therefore, means that the quiet sounds don’t get filtered out. You will still hear them but in a lower volume. The loud sounds like dogs barking or traffic will be audible but quieter.

A practical example of how soundproof curtains work is when you play music on your mobile phone. The sound is usually loud when holding the phone in your hands. But what happens when you place it under your pillow? You will still hear the music but more quietly and comfortably.

And why is it so? Because the pillow acts as a sound reducer as a soundproof curtain does. Instead of blocking the noise entirely, soundproof curtains usually make the sound die out, making it pleasing to the ears.

That is why they are perfect in reducing echo in a room, but they do not decrease the noise decibel levels coming into the room. But this doesn’t mean they don’t make the room quieter. They do, and that’s why they get referred to as soundproof curtains.
