I don't know how it would effect the sound in the room. I know it would not effect the decoupling drywall.

They sell those ez-ancor that work very well in tying a bolt point to drywall. Now the secret is to have enough of them over a large enough area that the force is spread out and not onto a single point. So I suggest using 20 or 30 of them over the area that you have pictured. Now the secret part of it is that you use them to affix a 5/8 piece of plywood that is the size of your shelf to the wall. If you have a bunch of those ez-ancor's at 1' spacing, then any force be it downward or torsion will be spread out over such a large area that each ancor will be pulling at most 1/4 or less of it's designed limit (that has a larger safety factor already. You then attach the shelf to the plywood that had a much stronger holding capacity and all is good.

Done it many a time and it works very well with no issues.

edit: if you want to be really secure, when putting up the plywood, put some of that PL400 industrial adhesive between the plywood and the drywall and it will go nowhere.
