Hmmm….  Have you thought about talking to your neighbor?  I would think that would be a lot better than stomping and making such an impression that your neighbor is forced to file a complaint against you. 

Your neighbor may not be aware of the problem it is causing you.  Your neighbor seems to be able to sleep with it on, so it may not seem like a big deal to them.  Maybe you could approach them quietly and politely to ask that they please turn off their fan during quiet hours. 

Personally, I think you’ll get a lot more accomplished by communicating with your neighbors. 

Nighty nite!

That is perfectly sound advice.  I can only wish that more people would take this adult approach.

So rare to see people act like real adults.

I have the exact same problem. I didn’t know where it was coming from, so I asked all adjoining neighbors. No one had a clue. I endured a couple more week,s then sent a letter to the adjoining neighbors. The neighbor below realized it was her ceiling fan. She was good for awhile, then I started hearing it in the late afternoon, early evening, late into the evening. And I’ll admit, I did use heavy steps more than once, which she complained to me about. Then the noise got so bad I turned the tv to an off-channel (=white noise) and that drowned it out somewhat. Finally I sent another quick note asking if that was her fan (because you can’t be totally sure in an old apt. building) We’ll see, but she hasn’t responded, so I suspect it was. I wonder if she’ll lay off. Well, new job, so time to move on once the money is saved up.
