Greenvent Metal Bi-Absorptive noise barriers

Listing ID #7149021

two layers of absorptive material to reduce noise levels. the first layer of material absorbs the high-frequency sound waves, while the second layer absorbs the low-frequency sound waves. this combination of materials provides a more effective noise reduction than a single layer of material.
bi-absorbtive noise barriers are typically made of a metal frame with two layers of absorptive material sandwiched in between. the absorptive material is typically made of a sound-absorbing material such as mineral wool, glass wool, or acoustic foam.

here are some of the advantages of using bi-absorbtive noise barriers:

• they are effective at reducing noise levels over a wide range of frequencies.
• they are relatively easy to install and maintain.
• they are available in a variety of sizes and styles to meet the specific needs of each application.
