Sell house directly again - Prepayment penalty

I would bet that it wouldn't bother you anymore then.

okay what is the bet?

That is truly not high. It is just constant and unchangeable. A whisper-quiet refrigerator is under 40db, a quiet residential street at night is 38db. If someone were hypothetically to advise you to move to a quiet environment (e.g. forest), then the forest noise would probably be louder.

It’s not the volume, but the noise itself. As written above, volume per se doesn’t bother me… We also have a very loud wine cooler here .. doesn’t bother me. By the way, I would love forest noise that is secretly my dream… to live by the forest. But here that is not affordable / feasible.

So in my measurements on our property, it was basically continuously 37-40db during traffic breaks, even when there was really no traffic at all - simply due to the ambient noise. Objectively speaking, it is therefore not "loud" at your place or my app is much more sensitive / shows too high values. I can't really understand that your friends confirmed to you that it is supposed to be "very loud."

But you yourself also wrote that it is more about the noise for you. I know the feeling too, but if I were you, I would really try to see if the problem solves itself over time.

What if you install a water feature? The splashing, bubbling, or rushing might be able to drown out the noise.

Good idea!

By the way, I just measured in the old garden. 24-26 dB. So sorry, then it is loud here…

So sorry then it's loud here ...

No, it may be louder in comparison, but it cannot be loud according to decibels. It is your comparison. People make comparisons: before, after... better, worse, or maybe better? Wait and see, do your thing. Install a decentralized ventilation system in your bedroom and set up a trickling fountain if the imaginary sound of the sea doesn't work. See where you stand next year.
