Acoustics has nothing to do with "vaudoo science"
You are misguided completely...
But if you think that some panels on a wall solve all acoustics problem you are right ... They do not... But that does not means that acoustics is a superstition created by audiophiles.. Read a book ... 😊
Lots of the acoustical treatments are voodoo science with results that may not do very much most of the time and actually served to dampen the room sound quality
