Issue with neighbour

I think you might need to give more information on the type of noise or sound being made or else every guess and potential yet irrelevant solution under the sun may be offered.

My neighbours yard adjoined my gable wall. I had no visibility into that section of yard where a racket for hours every evening used to drive me nuts. I eventually called into them and they explained it was a treadmill for dogs that they were training. I asked them could they move the treadmill over to the far end of their yard as placing it against my gable created a constant vibrating rat-tat-tat noise directly onto my wall that the treadmill was resting against. It reduced the sound by about 95% so made it bearable I'd never have guessed in a million years what the noise was nor realised dogs actually got trained this way if I hadn't called to the neighbour. The neighbour moved out shortly after as did the dogs and noise thankfully.

TL: DR contact your neighbour and amicably explain the situation. There's a chance they will address it if you explain your concern.

Is it a coffee grinder

Wtf. Mentally unwell or not, that’s not acceptable. If the bowling goes on for days it also means that the person is clearly not getting the help they need. Call the police because you are “worried” about this person.

A little off-topic here but my query is also about noise-an unidentifiable one which goes on continuously in a building. Not loud, no variation in pitch or tone, but you are aware that there's something there! Not pleasant!

My friend used to listen to his radio in his apartment in the evenings. He received a complaint from the management company about noise disturbance. He was surprised and he didn’t think that it was loud at all. When he realised that it was disturbing other tenants, he switched the volume right down. Sometimes, people are just unaware

So what? They clearly need to find the right treatment for said person. They can’t just expect neighbours to tolerate excessive noise when the sick person has an episode that lasts days.

Did I say they should be sedated? No, but you go right ahead and put words in my mouth. Because drugs for mental health either do nothing at all, or fully sedate in your world of absolutes eh Addle?

Also there's no qualifications required to know from the description given that this person is not well, and if healthcare services haven't visited then they absolutely should.

These are not a controversial points. Wellbeing of people should be checked.

Multiquote, read the post above yours in my post, and relax.

I lived in a really nice apartment complex for 7 years. It was a really well-located place. I was extremely happy to live there. Then, the pandemic started. New neighbours moved in. There was constant noise. Some asshole decided that they would do their gym session at 4am every morning. Multiple neighbours complained to the management company. The company lied to our neighbour and said that he was the only one to complain (I forwarded him the emails I sent to disprove their lies). One evening, it was so bad, a neighbour below us called to our apartment, asking if we were the people causing the noise. She had reached the end of her tether. We explained that it was the people above us. Yet, every time that these people were confronted, they brazenly denied it. I started to really hate our apartment. I would go into work sleep deprived. Generic “please be quiet” emails sent to all residents by the management company were utterly useless.

In the end, it was the spur to us to leave the apartment and to move elsewhere. It was just awful!.

It went from me living in my dream place to a nightmare place that I wanted to avoid.

unfortunately ireland currently doesnt have the services to deal with such situations appropriately, i know a chap with schizophrenia that screams the house down on and off throughout the day, hes largely left alone, i use to pass him walking the country roads a lot on his own, this is truly where we re at in regards mental health issues, services have effectively collapsed during covid....
