The simplest method to compare these data sets is to select the "200 Hz Interpolations" and plot them as a function of temperature. I have done that individually in the attached WORD document. The "200 Hz Interpolations" are a simplification of the total data set, but it is an accepted format in the Detoit Automotive industry, in general. So, it's at least a good first step in viewing the data for most people.
Print the attached WORD document and then hold each plot up to the other......... Place one page on top of the other. Compare the plots.......
Both quotes are from the third party that did this testing for us. When he refers to the WORD document attachments they are the 2nd and 3rd pictures above.You will notice that the data set for the Audio Technix and the data set for the Second Skin Damp overlay almost perfectly. Their performance profiles (as a function of temperature) are almost identical. It's surprising how similar they are, in fact. Almost identical.
