Hi Everybody,

I've been browsing this forum for a few days and have read quite a few threads but have not been able to find the answer to my question.

Here is my situation:
I am a therapist and a few weeks ago I took a job with a group practice of therapists.
The room I was assigned looked really nice and I was very excited about this new job...
Until the people next door started their appointment!
I could hear nearly every word...
So I bought a sound machine and turned on the air conditioner, but then it was too difficult to hear my clients.

At first, I thought that the walls were just too thin.
But my curiosity overcame me and I peered behind the curtain hanging on the wall.
I figured that the paint on the wall was messed up or there was some defect that needed to be covered up.
Instead, I found a double doorway, with 2 doors right next to (horizontally) each other, that opened in opposite directions.
So, when closed, the doorknobs were almost touching.
The other thing is that it appears there had been some prior attempt at soundproofing -- some type of drywall? was covering both doors but there was almost 2 inches of space (there was room for 2 inches of thickness in potential soundproofing materials) between the drywall surface and the doorway molding surrounding the doors.
If my description is confusing, let me say it another way -- I have 2 inches of depth to work with before the soundproofing materials would be jutting into the room -- after using more than 2 inches of insulation, the materials would no longer sit flush with the doorway molding.
I went into the adjoining room and the doors sit flush with the molding in that room.

Can anybody offer me advice on the best way to soundproof these doors?
Since the room is rented, I cannot remove the doors but I can certainly fill those 2 inches of space with soundproofing materials.

Thanks in advance to anyone who can help me.

I am sorry I am not good at describing these things.
The doors are not adjoining doors like you would find in a hotel, but they are french doors and the depth of the doorway allows for soundproofing materials 2 inches in thickness that can cover the doors.

Due to your situation, I would recommend making a large plug like you would for a window as a temporary solution.

http://www.soundproofing.org/infopages/windowplug.htm

Use 1 1/2" SSP Mat with a backer board, you will need to cut out where the door knobs are. It would be better to remove the knobs and plug the holes.

I dont think just doing a transom seal at the bottom and seal tape will give you enough reduction.

I do not think the doors are made of glass, I think they are regular office type doors, I just wanted to clarify that they opened like French doors.
Does that change your advice?

Thanks.

Does not change my advise, It would not surprise me if they are hollow core doors and since you can't change them its not worth trying to seal them just seal off the whole opening, This will be a very large plug but it is removable, the door knobs are my only concern you might have to go with 2 " thick with backer board and have it stick in the room a little, covering it up with your curtain.

What would you use to plug the holes left by removal of the doorknobs?

Someone told me to install Quietrock.  What is your opinion on that material?

I guess I wouldn't mind if it jutted into my room at all, since I'll wind up covering everything with a curtain.
In that case, is thicker better?
How thick would you recommend for the best sound reduction?

Thanks.

You can make 2 plugs out of the same 2" thick SSP Mat for the door.
http://www.soundproofing.org/sales/prices.html
first chart you see. 2" thick foam.

Quiet Rock is good Mass for airborne noise, for it to work correctly you have to install it in a permanent fashion caulking and sealing it in place...
Quiet Rock is not really a temporary fix and will not be easily removed if installed correctly.

Thicker is better, just keep in mind the main goal is to achieve an air tight seal around the entire door way. This is how the plug is effective.

Thanks so much for your advice Randy!

I have 3 more questions:

1) Should I try to seal all cracks with caulk in the doors before the SSP Mat is assembled?

2) What is backer board (does that come with the SSP Mat?)

3)I was looking around the website and came across MLV with 1/4" closed cell foam.
Does that have better or worse sound reduction than the 2" thick SSP Mat?
If the SSP Mat does not reduce the sound enough, what additional things could I use on top of it?

Thanks again,
Jess

Yes seal anything you can, this will make a difference!

2) What is backer board (does that come with the SSP Mat?)

Backer board does not come with mat, you can buy at home depot or lowes.
Sound deadening board or homosote.

MLV with 1/4" foam is an underlayment mainly for carpet, but has been used in wall systems for added soundproofing. In your case adding additional material will depend on if the plug extends past the wall and into the room, if it does im not sure how much more gain you will get from additional material. But if you do you can add a layer of MLV to the backer board for added mass. But I think the plug should work fine for the type of noise your dealing with.

So the SSP Mat would be facing the doors and the backer board goes on the outside of that, facing me?
