@shiro It is always good to find a solution to solve the issue properly and permanently. I have had similar problem in the recent years which I was not able to avoid. They had entire nearby blocks demolished and rebuilt. The only solution for me was using silicone earplugs while working and sleeping.
@AliMirjamali This is not a whole block though - just one asshole who cuts a lot of wood and drills and whatever in a tiny flat with very thin walls.
@shiro Maybe you could look into city laws on urban construction hours. I am in a different continent but we have local laws to prohibit construction before 9AM and after 7PM. We could report them to municipality if they violate this timeframe which will result in heavy fines.
@AliMirjamali Already done that, police came, now he stops at 8pm but took that as a “I have the right to be an asshole during the whole day and not care about people around me” -_-
@shiro If he really uses this as a workshop, your landlady should be able to do something about it despite corona.
1) Write a protocol about the noisy times (day + kind of noise + time noise starts + time noise stops)
2) You are entitled to reduce your rent payments. Check online for how much; AFAIK 30% reduction are appropriate.
3) Maybe noise reducing headphones can help. However, loud, high pitch noises are not entirely filtered by those.
4) Talk to other neighbours. Probably you're not the only one being disturbed by these sounds.
(1/2)
5) In the end, there might be no alternative to moving out. But as you say, that's not an easy task in Berlin.
Good luck!
I have had panic attacks due to this, sometimes burst in tears when the noise starts. There is no end in sight - he has been building for months in his 40sqm flat already, if this was about fixing something it would be over already. I can only assume he uses it as a workshop.
