Is room treatment a science?


What dictates room treatment?  
Many options are available but trial and error can be pricey. I'm a happy tweeker  seeking knowledge and experiences.
Thank You for your thoughts. Long live HiFi !

Duke,

Thanks for sharing the two article, very informative indeed. Anyone serious about audio should address room acoustics before they think of upgrading their components. GIK Acoustics value driven products and their true desire to help their customers is commendable.
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

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.
