Soundproof against neighbor in a townhouse
We live in a terraced house built in 1959, and in 1963 the upper floor was furnished. Now we have a neighbor who has installed a fan that we can hear in two bedrooms on the upper floor, as well as in the living room and kitchen on the lower floor. Since it is the neighbor's garage that is attached to us, only the lower floor has the neighbor "wall to wall." On the upper floor, the neighbor's house is not "wall to wall" but has open space. However, the sound is also heard in the bedrooms.
We would now like to soundproof against this neighbor. We have briefly spoken with an acoustician more generally about how to soundproof and have concluded that we might build a new free-standing wall with an air gap that is anchored in the ceiling, wall, and floor. Not in the existing wall. We were thinking of having a 200mm air gap in one bedroom and 20mm in other rooms. We plan to bring down ventilation ducts from the attic and were thinking of having a larger air gap so we can have a smooth wall to place the vent channels.
I am now wondering if anyone here can answer if this is a good idea. Will it dampen the sound and is there a risk of moisture in the air gap created by this?
Are there any other ideas on how we can solve our problem with the fan being disturbing?
The lightweight concrete is blue concrete; we haven't done a radon measurement yet, but we guess it will be around 150-300 Bq/m3. Is there anything we can/should do in connection with the soundproofing that can affect this in the right direction?
The plan is:
- Install metal studs in the ceiling, wall, and floor, then studs cc45
- On the back of the metal studs, place strapping tape to hold the insulation in place
- Insert Isover acoustic sheet Piano between the studs
- Install a 13mm gypsum board
- Install a 12mm construction plywood to facilitate mounting things on the wall
- Install a 13mm gypsum board
- Paint or wallpaper
I have made some pictures below that describe in more detail how the existing wall looks on both the upper and lower floors. As well as our idea for an additional wall.
Can anyone help us?

Yes, we have talked to the neighbor. They have reduced the speed of the fan, which made a difference. They also had a technician to see if there was anything they could change to lessen the problem.
Something not mentioned in the original post is that we will be putting drywall on the walls downstairs, and upstairs we are in the process of putting drywall on all surfaces. So we already have some work and expenses ahead of us. Additionally, we would like to soundproof a bit apart from the fan.

It is a radon extractor, the installer of the extractor has been to look at the fan. They couldn't do more. I am aware that the resonance also travels in the floor joists etc. But the hope is that it will make a little difference.
In the living room and kitchen, we want to do something because we want to have gypsum and plywood in the wall to have something to easily attach to, and those walls have wallpaper directly on the concrete wall. So in these rooms, it's not much extra work/money to build a new wall according to our plans. A plus is that the overhearing between the houses will be less. So the question is if there could be problems with moisture or similar if we build a wall outside the existing wall?

I think it darn well should be possible to solve with some form of vibration dampeners. I suffered from the noise from the compressor in our heat pump and changed vibration dampeners and the difference was enormous. Actually, our new heat pump, also Nibe, makes more noise than the old one, so I'm going to use dampening mats etc. there too.
