Acoustics is where I have been doing the most study for about thirty years (the horticulture (a matter of learning history), photography (dipshit easy math), art (no rules apply, anyway) interests are all negotiable without any thought). Some acousticians are well ahead of me in presenting theory, but they are dumb as rocks in practice, which I know, well. I have much to offer the industry still, but I have to make my thoughts felt in a language for which I have little knowledge, due to my own lack of education. Sometimes, it sucks to be "gifted" (used for lack of a more flattering way to express obsessive interests), because you think you can help, but you can not express in their language what they have overlooked.
