Question: How to determine the isolation the floor will provide when patched (it currently has holes in it)?

I also looked at my floor in more detail and it looks like it's 3/4" decking directly over the floor joists. There is then a 1/2" drywall attached to the bottom of the floor joists. The electrical is run in metal tubes attached to the drywall (so if I want to replace the drywall I also have to take down and then put back the electrical).

I'm hoping to leave this structure as is and add to it. Thinking about adding a 1/2 of plywood over the decking and then some laminate wood flooring on top of that.

On the bottom of the floor I'm hoping to blow in insulation as currently, the cavities are unfilled.

Right now there are holes in the wood flooring in some places, as well as in the drywall attached to the floor joists. So I don't know if measuring the levels when inside the room and making noise will be super useful until the holes are patched? As I wouldn't be getting the isolation the existing structure will provide once mended.

Quick Update:
As a starting point, I took the model John graciously supplied and began modifying it for my room.

I still need to work on the back half of the room with the bass trap and the door.

If you end up building it as a room in a room, then use the MSM equations.

Yes. But, usually the tubing comes apart in pieces easily.

So you're saying that whoever is below you has 1/2" drywall for their ceiling? I doubt you can mess with their space.

"bottom of the floor"? Now are you talking about your ceiling or are you meaning you will remove chunks of your floor to blow insulation under it?

Always take measurements.

So to confirm, you are NOT doing a room in a room, correct?

I still need to work on the back half of the room with the bass trap and the door.

Your mix position is not centered from left to right. That's a must. Also, having your L shaped desk like that is also screwing up your symmetry. You need to do ray tracing. It appears as though you might not achieve a true RFZ with the current soffit and soffit wing angles. Your soffits looks mega shallow. You could probably bring them further into your room which would help you achieve your ray tracing goals and at the same time give you a larger baffle. Of course, this will also allow you to actually fit your speaker enclosures into the soffits!

That corner back door has to stay there?

Hi All,

Thanks for the advice given so far on this forum! This really does feel like a rare positive space on the internet.

Unfortunately, I've been woken up the last two nights by neighbors walking on their floor (my ceiling) around 1 AM . This has led me to the conclusion I need to break my lease here and find a different space.

I hope to be back in a few weeks once I've moved into a new space, with a new SketchUp model.

Best,
Chad

I'm sorry to hear that Chad

Good luck with your search and I'm sure you'll find a great place. At least you know what to look for now so that you can have an awesome space!

I'm sure I can speak on behalf of everyone and say that we are excited to see you back and ready to rock!

Greg
