The 12 ” block has a Sound Transmission Class (STC) of 55. We estimate that the 10″ block has an STC of 53 based on a direct interpolation. These results are better than Soundblox®, the leading sound absorbing masonry design sold in today’s market. The NRG Block is the only block that has a solid façade yet still will provide a superior noise barrier to any other block on the market.
