Stop Sound leakage from the door

Dear community,

Before anyone says anything, yes I did look up similar posts, though they did not answer my question as I believe is somewhat unique.

I am renting a condo, the sound leaks through the home enterance. I want to stop that. To give you an idea of the room, well, its a rather long 18' room, at one end is the enterance, at the other is my speakers. (Basically everything is set up in my living-room/kitchen.

I am thinking of building of a floor to ceiling (any other ideas are welcome) sound insulation panel using one of the following materials as base:
1. OC 706 unfaced 2";
2. OC Thermafire 4"/6";
3. OC 705 unfaced 4"; or
4. OC 703 unfaced 4".
I want something that is very safe to handle (doesn't require a mask or gloves); primary concern for this is that I never want to worry about "oh I'm breathing in the fibers". Additionally, something that doesn't gas or it's very safe (i.e. Thermafire which is formaldehyde-free).

I'd really appreciate your guys' help.

Let me know if you need more information.

Cheers.

Insulation doesn't provide meaningful isolation. It takes mass to stop sound. Read up on sound isolation construction techniques.

You need door gaskets and a drop seal for the door bottom. You should be able to surface mount these
Components with minimal damage.

Doubling the door in the same jam and replacing both with solid core doors works pretty good. In addition,
I added an extra 1" of closed cell foam to the inside of the outside door, which sealed the air gap between the doors.
I also added three layers of 1/8" MLV to the outside of the outside door.
Sealed both doors with closed cell foam weather stripping.
The seals are very important too, think of a watertight seal as a ideal preferred case.
This worked extremely well and I have a measured TL of 79db.

Even better if the inner door is smaller than the outer one and the jamb is built out to fit it. Bank-vault style.
