Not exactly the same situation but have had neighbours that has the habit of throwing a loud party once in a while without telling anyone.
Next time the were setting up I went over with a bottle of popular tipple and asked them kindly please to let us know ahead next time, so we could plan around it. After that they were very becoming and even polite about it.
What I mean to say it's that even if anger is building up at your end, you should try your best and be nice, they might not (weirdly) be aware of the fall out of their behaviour.
I once had a party when I was younger and didn't let the neighbours know beforehand. The next day the guy from next door came over and I was expecting him to give me a telling off about the noise. Instead he asked me if me and my friends had moved his girlfriend's car to the other side of the road. I'd never even spoken to him before, so of course I didn't have a key to the car. He said it was a small car and a group of us could have bounced it across the road. I told him that I had no knowledge of that happening and maybe his girlfriend just forgot where she'd parked it but he went away looking unconvinced. Never spoke to him again before we moved out and I think he still believed we'd moved it.
This sort of issue is why I will never live in a shared space again. I had the neighbor who's girlfriend screamed like a porn star at all hours of the morning. I mean, great for them, but could ya not do it with the windows open at 3am? We also had issues with their sound system rattling the walls. They were pretty polite about that one, but it just kept creeping back up. I suspect it was a bass unit near a wall and it can be hard to understand how much it affects nearby people. Eventually, we moved. Now live in a detached single family home and fuck ever sharing a wall/roof/floor again.
I disagree with your easy answer. No one should have to wear noise canceling headphones just so they're not being kept awake by their neighbors. I agree with talking and sound dampening.
I complained to the landlord and was unheard, I complained to them and they said "ok" and continued. Several complaints later I threatened to call the cops, it was a proper house party, middle of the week, they were clearly crackheads with no jobs, there was tons of people, alcohol and drugs.
This was their very first night.
Since then we interacted many times, all of them extremely unpleasant. It eventually evolved into a war where I would bang on the ceiling at random times of the night, and I hooked my guitar amp up and blasted music directly into the ceiling all day and all night until they came down and started bitching that all of this was giving them panic attacks. That felt satisfying!
Eventually I managed to get the landlord to agree to evict the fuckers, due later this month, hopefully the leech follows through. We secured a temporary truce but they've been getting more and more brazen with their noise levels, I've placed the amp back up to the ceiling so it's ready for the right moment to start blasting.
Some other ideas I had is spam deauthing their WiFi.
[...], such gadgets are built around vibrating motors originally designed to run industrial sieves. They come with multiple modes: vibration only, pounding only, or a combination of the two. A fourth option activates both, along with other random sounds including static, persistent knocks, and even piercing shrieks.
The floor-shaker serves one purpose: when installed on the user’s ceiling, the deafening noise it makes is projected into the house above
I have considered exactly this before but held off suspecting that it would bother neighbors below. Looks like it ruins the lives of everyone in the building. Glad I didn't set one up.
Someone I knew was living in an old building with old-timey fuse boxes placed outside the apartments. When she got tired of her idiot neighbours partying on a weekday night for the millionth time despite being asked to dial it down she finally had enough and went to the fuse box and took away all the fuses to the neighbour's apartment.
Update: Thanks for the advice. Particularly, they may not realize they are loud. That was something I hadn't considered. I knocked on the door, and no one answered. I know someone is up there, because they walk like a dinosaur. Based on their steps during the day, I imagine they are quite heavy set, know how loud they walk, and could be embarrassed to open the door. I will try again later, and hopefully a positive update will follow.
But, if this turns into a game of noise, I have a solution: make them louder. I have access to an ultra sonics lab. They'll be loud enough I won't need to call in a noise compaint. The rest of the complex will come with torches and pitchforks. Though I believe this can be solved diplomatically.
Keep in mind that they may have a social anxiety which prevents them from answering the door. When I was younger, I pretty much never answered doors and just stayed as quiet as possible until the knocker went away.
Are they Mormon missionaries? I swear they put a bowling lane in their apartments. This is from two different sources. One of which I got to witness myself on several occasions.
I used to knock on their door and ask nicely and apologetically and they stopped for a while but then resumed :/ It's not entirely their fault cause the walls were pretty thin but they could have gone somewhere else to hang out with their friends at 3am.
