Totally understand and agree, but the excel spreadsheet you provided expressed the difference in terms of decibels. Again I ask how you get around the fact that there is a .14 dB difference between wood and concrete, and that when that is extrapolated to 1440sqft it amounts to a 3dB net difference? You haven't answered that question. I'm not asking about the coefficient. You're right, that is "dimensionless" so to speak...so are degrees of separation; three degrees of difference is the same at one foot as it is at 100,000 feet, but the distance the two points are from one another will drastically change. Please explain how my metaphor expresses a different truth than your statement.
Secondly, you also didn't explain how you would extrapolate the test results to a larger scale and what the data would mean in view of your dismissal of Bryan's extrapolation of the data in your spreadsheet.
