I absolutely agree with your comments on automotive interior architecture, there are endless variables that affect the propogation and transmission of wave energy throughout the vehicle, further compounded by even the very dynamic nature of the vehicles many possible geometrical configurations. This "listening room" (to compare what is being done to a home audio setup) that we are trying to create changes inherently everytime a window is adjusted, a sunroof is opened, a seat position is changed, and profoundly as the barometric pressure fluctuates.
I also agree that while extensive knowledge of physics allows an enthusiast to better understand the results of actual experimentation within our "labs" (vehicles), one cannot possibly fully predict the behavior of drivers, and the waves that they produce in any vehicle. Prior knowledge of science helps us plan, but new, further understanding of science (through the learning that takes place prompted by data gathered from experimentation) is what allows us to move forward and make improvements.
One more quick comment. (PV this part is not directed at you) Although I am new here, I would like present one idea. Instead of offering a purely negative feedback, or feedback that is overly simplified and in absence of sufficient explanation, try offering a comment that is well grounded in some type of research, or honest and accurate prior knowledge that has been tested sufficiently, rather than a resonse driven by sarcasm or satire or the likes of. I would speculate that the amount of learning that takes place in this forum would increase. I just want to understand the most possible, and hopefully help others do so as well in the future. For reference, this thread has not been a problem, and has been very helpful as stated above.
Just my personal insight. Take it as you wish, for whatever its worth.
Thanks again for all of the input.
