Hey, don’t get me started!
I mean that literally.
Please, don’t get me started. I don’t have the time to dive into another new hobby/field of endeavor/relentless obsession.
I’ve long been fascinated by sound and vibration but I’ve never really gotten past the basics. It’s a
hugely complicated corner of science and engineering.
The reason you’ve seen a lot of half-baked posts on the subject is that it’s so specialized. Most of the people you see posting about it are amateurs, enthusiasts and Joe-Blow-off-the-street guys who are playing and experimenting without much actual knowledge.
There aren’t all that many people out there with real expertise and they aren’t hanging around in online forums posting everything they’re doing. You’re mostly going to find their work published as academic or industrial research.
Which is not to say that hobbyists can’t be successful, many are. It’s just that you can’t easily differentiate their “dude, this sounds much better” posts from the next guys’ because there’s no objective basis of comparison.
Just as a taste of what goes on in the field:
