Is room treatment a science?

Actually anechoic means no echoes AND no reflections. All reflections are not echoes. In most rooms some reflections are beneficial whereas echoes are not. It’s probably not a good idea to turn your room into an anechoic chamber, but who knows? I certainly never tried. I keep seeing people saying that you shouldn’t. Echoes are easy to eliminate by using the clap hands 👏 method. It’s not rocket science, guys. 🚀

Sorry for such stupidity but I've got a setup with some xrt 30 Mac speakers in a 40 x 40 room probably do not require any room treatment for this type of space any insight thanks

Is a $4,000,000,  2000 seat auditorium trial and error or scientific.?

It depends how they went around the volume of bodies expected to be in and material that clothes would be likely made of while there.

yes, it's a science. But you can diy, cheaply and simply and hear an improvement/difference.
It's easier to take brightness and echo out of a room, I would think, than the other way 'round.
Having a large rug on the floor helps.
Artwork on the walls helps.
Seating arrangement helps and the style of seating helps too.
I really notice a difference by pulling the curtains across the sliding glass doors. Stops reflection and harshness..
