We have a two story house built in the early 90s and I want to use one of the rooms as an office. I'll be working from home the majority of time for the significant future so I would like to improve it's sound proofing
The problem is this room is directly above the kids play room, which is also attached to the kitchen which would have the radio/music on a bit(we removed the double doors between kitchen and playroom)
In its current form you can hear people talking in the room below, not even that they are talking, you can even hear what is being said.
The house is block walls downstairs with wooden timber frame internal walls upstairs. It's a timber frame floor upstairs too.
Currently there is no floor finishing upstairs, just solid timber floor boards. I do not know if there is anything between the floor joists (existing insulation), I assume not. You can hear the talking through the floor (as opposed to from the hall)
The room is a corner room where one of the walls has an ensuite (has tiles, over the kitchen) and also connected to the hot press (not via a door, just share a wall). The other wall connects to the hall where the stairs is. The doors are fairly cheap feeling doors.
Do people have any advise on approaches for improving this? I would also love to hear people's stories if they did similar and it if was worth it.
I don't need it to have recording studio levels of soundproofing or anything and I'm also not concerned about noise from the room going anywhere else (footsteps etc) but I would like to significantly improve the current situation.
I have access to cheap floor coverings, so I was thinking of maybe starting with loose laying something like padded carpet tiles to see how it goes possible even with sound dampening underlay, but I really get the feeling to make a significant impact I need to put acoustic insulation between the joists.
I'm relatively handy at DIY stuff but I've never had the need to lift floorboards before so that will be a new adventure
I certainly don't have an unlimited budget for the project and would like to keep it as "cost efficient" as possible, but happy to consider any options if it's the right way to go.
