Sound Blocking/Barrier products typically involve mass. These products help block noise from traveling from. one area to another. Sound Blocker/Barrier Products carry a comparative STC number that reflects the approximate Dba reduction with use of that product.

Remember - anything water can pass through - sound could pass through. These products can be of use in Cafeteria's and Resturants where sound transmission to other rooms is a problem. The use of composite materials that have a layer of Barrier material with the addition of at least one layer of absorption material is also a nice solution that can block and absorb. Products are also available to block sound where floor-to-floor sound transmission is a problem in Cafeteria's and Ressturants.
