It's going off the structure-borne noise reduction and the transmission loss performance of your avg barrier decoupler product. Keep in mind that 10 dB is half as loud to the human ear.Actual testing of the substrate and everything that's involved might be different. Needless to say, barrier performance can be predicted using a simple math equation. Once you get into absorption and everything else, then it becomes very difficult to model it out. This is where independently tested materials are valuable.</blockquote>
