Sound-absorbing concrete block

How efficiently concrete block does this is measured by deter-mining its sound absorption coefficient (SAC). If a surface were able to absorb 100% of the sound waves striking it, its sound absorption coefficient would be 1; a surface absorbing 65% of the sound waves striking it has an SAC of .65. The higher the SAC, the more sound absorbed by ...
