I have a bit more experience with an acoustic treat. I hear its demonstrations from vendors who recommend their products. It helps to know how your room responds to sound using an RTA mic and noise measure software. Sound travels through the freaking air by vibrating it. In every direction, the music you listen to reflects and goes through surfaces like walls, tables, floors, and ceilings. It reverberates, echos amplify and or cancel sounds out. A well-treated room will simplify the production process by giving you the truth of your mix. Un-treated places tell audible lies for you to mix, and mix, and mix...
Therefore, it helps to have a goal to accomplish when using acoustic treatment to create the sound of your space. Even if your studio is a bedroom, you should take note of its natural tone. It helps to know how it affects what you hear coming out of your speakers. I would also recommend having more than one set of studio monitors and in different sizes. All studios should have a subwoofer for mixing lower audio frequencies. It will be time-consuming to mix without these tools.
