What Is the Most Effective Sound Barrier?
Your sound barrier should block as much sound as possible. To be effective, that barrier must have a high mass and density. Therefore, concrete walls are the most effective sound barrier. However, there’s more to consider when soundproofing a room.
While a massive, dense barrier will block most of the sound energy that hits it, a hard surface will reflect the sound wave back into the room. Concrete walls cause echoing and reflection that do not reduce the noise in a room. Therefore, a material that combines sound-blocking capabilities with absorbency is the best type of sound barrier.
At Soundproof Cow, we offer numerous materials that block and absorb sound. Products like fiberglass composites, foam composites, mass-loaded vinyl (MLV) barriers and acoustic quilts offer a premier blend of soundproofing and sound-absorbing capabilities.
How Effective Are Noise Barriers?
Noise barriers prevent a significant amount of sound transmission. We test each product to assign a sound transmission class (STC) rating, which describes the ability to prevent transmission on a scale from 25 to 65. A higher rating equates to lower noise penetration. We carry numerous noise barriers with STC ratings exceeding 30 to prevent transmission in industrial and residential environments.
