Great presentation Mr. Sauro. Thank you from the bottom of my heart. Due to the disparity between formulas, charts, room or absorption calculators and actual results, my acoustic work(studio design) is largely based on empirical observation after experimentation. Using all available information, no matter how careful the plan is, you still have to measure the actual results(REW), and make adjustments. There is always a disparity between the math and the room, resulting in a lack of trust in those charts, formulas, and calculators. This is how I have proceeded for decades, feeling that acoustics is a nearly incomprehensible set of variable results that changes with every room. Only through actual experience using different materials and different placement in different rooms to solve acoustic problems based on measured results, can useful ends be achieved. The information presented here(excellent science) reveals why there are so many problems in acoustic design. The question about the believability of manufacturer data sheets caused me to yell out loud - NO !! Thank you for the confirmation(and the laugh). Empirically it's obvious if you ever do the work, but nice to have some science to back it up and explain it. Thank you, thank you, thank you Ron Sauro. I have learned a lot.
Please note that at 55:24 the equation in red color is UPDATED and not valid anymore after talking with Ron personally. Again thank you for posting this great video.. Ron is a legend!
It turns into a great life lesson at 1:20:00 time. Thanks Ron! Amazing lecture!
