Of course it helps !, although it is a complement, of the absorbent panels and bass trap, for you to consider. You don't need to buy the highest value ones. 🇨🇱✌🏻
No! You see it that way! And neither that you are going to fill the room with panels or if you are not going to create a dead room. And at the same time there are many materials and ways to create acoustic panels, be it absorbent, diffusers and bass traps. If you go to the cinema, look at the design of the walls. Practically, in concrete material with a half-layer of fiberglass foam covered with a cloth. This is the case in most rooms. And I tell you with respect and without the intention of offending you 👍🏼✌🏻🇨🇱
