The sciences of acoustics and psychoacoustics are applicable to room treatments.
I agree with @erik_squires ’ recommendation of Floyd Toole, in particular his book "Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms". Imo the third (most recent) edition is the one to get.
Another excellent source is Earl Geddes. His book "Premium Home Theater: Design and Construction" is now available for download free. Don’t be put off by the title - most of the book is applicable to high end two-channel. Just skip the chapters which obviously don’t apply to home audio:

Chapter 5, "Room Acoustics", is the most obviously applicable, and includes sections on Spacious, Localization, and Timbre.
I used to engage in armchair-quarterbacking recommendations of room acoustic treatments, until I spent some time in couple of rooms that had been treated by a real professional, Jeff Hedback. A real professional acoustician can tell you where you need diffusion, absorption, and reflection, and how much. (By way of analogy, a professional crossover designer will determine where you need inductance, capacitance, and resistance, and how much.) Jeff is still affordable and his company is called Hedback Designed Acoustics. Here is an article he wrote for GIK Acoustics, it is about much more than just diffusion, imo it’s very much worth reading:
