alex, I am in college.
lkonantz, it's funny, but just after I wrote, "I'm filing a noise complaint," the noise stopped, and, thankfully, didn't return for the rest of the night. Since I was so sleepy that night, and the noise did stop, I decided to not file a noise complaint. (I have filed a noise complaint before. Last semester. Several, in fact. Those noise complaints were not particularly successful in achieving a reduction in the noise. But that is another story, the results of which I have discussed before on these forums.)
UPDATE: Though there was the exception that caused me to angrily post this rant thread, the noise from the dorm next door, has, in general, noticeably reduced since I posted my letter to the door. In fact, I now believe, based on my past experiences with filing noise complaints, it may have been a more effective thing to do than actually filing a noise complaint. But in the case that the noise does start up again, as it did to cause me to start this thread, I am still prepared to file a noise complaint. A noise complaint may be effective. Even if not, at least I would have covered my bases if I ever have to make a legal argument about the noise because I would have both a.) contacted the noise offender personally and b.) filed a noise complaint (though to no avail.)
Now here is a new noise problem, one which has not been a problem before: since my original post in this thread, people (from a different dorm) have started hanging out in the hall just outside my door and making noise late into the night. I just can't understand why the hall is a better place to congregate and talk very loudly than in a dorm or in the so-called study room that is usually available.
