What's acceptable noise at 5am?

The neighbour isn't opposite, they're attached.

And if anything, as has been mentioned throughout the thread, noise going through a wallspace can become amplified, not muffled.

But whatever, it's all excuses at this stage.

I really doubt there are many (outside this forum of course) who would be completely unbothered listening to that at 5am every morning.

Yet it was loud enough for him to raise the subject with you.

You started the thread asking if it was acceptable or not, in my view, and from some others here, its not, but you obviously had your mind made up - or only wanted to hear that it was okay.

Now, you can decide to ignore him and go with everyone here telling you its okay to do whatever you like, hes a crank, blah blah blah, its no skin of my nose. I'm not your neighbour.

You're the one who'll have to live beside him after all.

@Mr.S

If you had actually bothered to read the thread properly, you will have noted that several people, not just myself, pointed out that the neighbour probably mentioned the microwave door slamming, to emphasise to the OP just how much noise he can hear coming from the OPs kitchen.

You must also have missed that the OPs neighbour is the parent of 3 small children who sometimes wake at night, so earplugs are not an option when you have young children to listen out for.

You're also projecting that just because the neighbour has complained about the newly acquired coffee grinder, that he will find other things to complain about. If there was an issue with the *insert boiler / pump / shower / car door/ here* before now, why didn't he complained already?

On the rest, we'll have to agree to disagree. I don't agree that grinding coffee beans at 5am is a normal household thing. 5am is still the middle of the night to some people.

I guess its a good thing we're not neighbours.

I’ve sold a house and moved due to noise issues but there was no other solution, the noise just couldn’t be stopped.

In this case the noise could be stopped but the OP is prioritising their coffee over the neighbours sleep. That’s a choice they have to make. It’s a pity the sound proofing is so crap though. Ultimately the regulations or shoddy workmanship is at fault.

One thing I’d say is sound proofing in this country can be so inadequate that people need to investigate as much as they can before they buy or rent. Especially when buying as I’ve learned the hard way.

I'm perfectly relaxed, thanks.

It's some others who want to continue to argue because I won't back down on my opinion that 5am is not an acceptable hour to be grinding coffee beans.

Thats what the OP asked for, after all.
