What is Acoustic Curtain and Soundproof Curtain

 Sound proofing curtains are made of heavy, thick materials like polyester, velvet, or suede that you hang above your window frame. They usually have a porous surface that allows them to absorb sound waves in order to make a room quieter. Soundproof curtains are much bigger than normal curtains: Curtains like this tend to be huge, with a drop length that can almost reach the floor, and a width far greater than the width of your windows.
This allows them to cover the maximum area around your window, which is where the vast majority of sounds will get into your house. This can make a major difference. Even having a small area around the window uncovered will let a lot of sound through.Soundproof curtains tend to be rough, porous and have very deep pleating: These things make a significant difference when you’re dampening a sound. As we already mentioned, sounds are a wave that travels through the air. When they hit something, they bounce off of it, and the flatter the surface they hit, the more cohesive the sound wave that comes back. That’s why you get the best echoes in places where there’s nothing to deflect those sound waves.
