Sell house directly again - Prepayment penalty

I would bet that the noise isn't coming from outside...

mhh what do you mean by that? We have open ceilings on the upper floor.. so you can see the roof beams. But we once stood by the window and the noise seems to be coming from there. Unfortunately, we don't have standard windows. That's why I'm a bit afraid of the price and the windows themselves are actually still great.

You can only hear the noise on the upper floor. Here we have 6.50 m high ceilings.

Your upper floor is a large resonating body. Let me guess: no carpet to absorb noise, hardly anything on the walls, everything clean.

Maybe you could try using acoustic panels?

mhh how do you mean that?

The windows - with a highway so far away - should already completely insulate the house from noise inside. Soundproof windows will, with near certainty, not change anything. Do you have a ventilation system?

That "helps" enormously that it is rustling. And finally, it could also be due to you and your psyche (no offense). What do uninvolved third parties say and/or what does a measurement show?

What use are opposing opinions from measuring devices or other outsiders to the psyche?

What exactly does "noise" mean?

Here in the Ruhr area, you can hear the heartbeat of the Pott almost everywhere, meaning that the noise is immanent as background sound. However, it is not a constant sound, but irregularly rising and falling, just like the traffic plus changing wind. A consistently loud noise can hardly have a street as its source.
