**Background info:** I live in a large shared house (more than 10 people). Honestly I would like to move but given my lease we're stuck together for a few more months. The company that rents the house tries to rent it out to international students or people on working visa. Though I've lived with several international people before (and had a great time) I noticed there seems to be barriers in this situation, probably from the fact that people aren't motivated to speak a common language given there's usually one other person who can speak theirs. I mention this because it seems very taboo for people to complain about anything or make requests (such as, "can you please not turn on the radio in the morning"). 

**Specific Situation:** I am being affected by the noise in the house. It is affecting my ability to do work and rest. I can hear a lot of it from my bedroom with my door closed. For example the person across the hall from me yells into the mic while playing computer games after midnight. Also a lot of one-off things like people ordering food and the doorbell rings close to midnight. 

**Question:** I know the first step to addressing the problem with someone is to simply make them aware of the issue. I find this hard because:

 1. Sometimes the noise is so short it doesn't seem worth it, for example the pizza delivery man ringing the door bell
 2. It's hard to find a good opportunity to address it. Many of the roommates I don't see for days at a time. For the guy yelling at his computer, I would rather not interrupt him at 1am while other people are possibly listening on the microphone. 
 3. Sometimes I don't know where the noise is coming from. For example if I hear music, I may not want to search the house if I'm in bed or trying to focus on work. 
 4. It seems to be taboo making requests with this group. Once I asked my roommate to keep his door closed while playing music and I felt he went over board with a huge apology. Also no one else ever makes requests of other people.

In general I believe it's best to address a concern as soon as possible, directly with the person involved. This isn't always easy in my situation. Am I doing a bad thing by waiting until the next day or ignoring some situations like the pizza delivery close to midnight? In situations where I'm not sure where the source of the noise is coming from can I send a text message to everyone? Would it be bad if I slipped a note beneath a specific person's door if they are yelling at their computer or talking on the phone at night? If not, should it be anonymous or signed by me?
