Hello everyone! I previously opened a thread asking about sound wave energy loss in aluminum discs based on thickness. I am looking to find out more about exactly how much using a disc that is twice the thickness of the other, (one is 1/8" and the other is 1/4") sound energy would be lost using the thicker one compared to the thinner one. We had some problems using the 1/8" one and we may need to use the 1/4" but I don't want too much sound to be lost in the process. Thank you!
