Try a cork underlayment with a Pergo or DuPont laminate floor with foam. DuPont Elite already has the foam attached, and it is an in-stock item at Home Depot. I just installed it in my coop in NYC because I wanted to minimize the sound to my neighbor below me in a room that I wanted to use as a work room/yoga/workout room. Prior to laying down the cork, my contractor screwed down all the squeaky boards on the existing old, oak floors. Google Pergo, DuPont Elite, and cork underlayment and you'll find useful information that may work for you. I donÂt plan to jump around but I wanted to deaden the sound as much as possible. A sprung floor (raised and on thick pieces of foam) would be the best sound insulation, but your floor would be raised so high that most of your doors would have to be cut down to open. I wanted a sprung floor, but the doors situation was a problem and it was 2-3 times the price of the DuPont Elite laminate. I wanted to use Pergo, but couldn't find it in stock anywhere and I needed it ASAP. If you want wood, this may not be the solution for you, but laminate was fine for me as it is for one room that I intend to use as a rec/work/work-out room. Note that laminates can have a clacky sound, but the cork does deaden the sound quite a lot so I think the person below won't hear it as much.

If the bathroom is between both bedrooms, you will still hear noise coming thru the doorway. It's so close. Preventing noise from coming through the wall is going to make the noise travel pattern more standard, more traditional and and therefore more acceptable to the average person. Yes, we all know that the only person to please is you, not the next buyer who may never notice this when they come look see and inspect. Perhaps this description is all you need to convince DH to tape around the electrical outlets and to add a Roxul or equivalent high mass high absorbency padding in the stud cavities. A better product than the old run of the mill pink or yellow scratchy fiberglass batts will make a small improvement (although anything is better than nothing). There are other products no doubt being sold in your local stores that are better than fiberglas batt stuff. Good luck in finding them. Perhaps the web site of your local stores will be the best place to start. Post again once you have found something.

We have a basement bedroom/office that we have been unable to use because it shares a wall/door with an air bnb/studio apartment and you can hear everything through it. We are trying to make this a usable space on our side for a guest room or an office where you wouldn't be able to hear the people in the other studio apartment having a normal conversation. We own the whole house (both apartments) and have chosen to subdivide it in this way. Just one of the walls is shared directly next to this attached studio apartment (the one on the right side of the picture). The other two sets of doors have the buffer of a closet then a bathroom on the other side. All walls consist of just studs and drywall, no insulation or anything. The shared door, which always remains locked, is a solid wood door but has some thinner panels and also an air gap under the bottom. This entire house was just renovated less than a year ago. We are willing to spend some money on this space including possibly adding a second door as a buffer (but probably don't want to spend more than 1k on the door by itself). My initial thought was to extend the wall that has the closet doors across and add a second door between the two different apartments so someone can still get through in case of emergency. What kind of door should I use for this? The floor is somewhat sloped so I'm wondering how I can seal the gap that would occur under the door? I think the new wall extension would want to have insulation inside it, so if you have any suggestions for that, that would be helpful too. I'm also trying to figure out if I should add insulation inside the closet walls that are shared with the bathroom for the studio apartment, or maybe an extra layer of drywall with green glue, or maybe there are some cheaper foam panels we could use and just velcro them on the walls in the closet? Are there any other products that work where I wouldn't need to extend the wall and add a new door? Thanks!
