Silk Fabric Revolutionizes Noise Suppression in Interiors: Researchers Develop Thin, Vibrating Material for Sound Insulation in Real-World Settings

Researchers from MIT and other institutions have developed a groundbreaking silk fabric that can suppress noise and create sound insulation in interior spaces. The fabric, which is incredibly thin, contains a special fiber that vibrates when voltage is applied to it. These vibrations are harnessed in two ways to minimize sound.

In one technique, the vibrating fabric generates sound waves that interfere with unwanted noise, canceling it out similar to noise-cancelling headphones. This method is effective in small spaces like ears but not in larger enclosures like rooms or airplanes. The second technique involves keeping the fabric still to suppress vibrations that are necessary for sound transmission, further reducing noise volume. This approach allows for noise reduction in larger spaces such as rooms or cars.

Using common materials like silk, canvas, and muslin, the researchers have created noise-suppressing fabrics that can be implemented in real-world settings. For example, these fabrics could be used to make dividers in open workspaces or thin walls that block sound transmission. Professor Yoel Fink, the lead author of the research, emphasizes the significance of creating quiet spaces with a thin sheet of fabric rather than thick walls.

The research article on the fabric was recently published in Advanced Materials, showcasing the potential impact of this innovative technology in creating peaceful environments.
