How to handle noisy neighbor in the morning?

I am currently in a residential neighborhood that’s been pretty quiet. Recently, though, one of the neighbors (we’re back to back so I’m not completely sure where the noise is coming from) has either the TV or radio on in the mornings–think around 7-8:30 AM.

It sounds like a Mandarin news or talk show. The volume is LOUD: I can hear it through my closed window. I think this person has the window or doors open perhaps while getting ready for the day or to perhaps to hear over the noise of the household or cooking or something.

It’s really obnoxious, but I don’t want to go outside and start screaming at them to shut up. I was thinking of writing an anonymous letter, but I was wondering if anyone had any other suggestions.

Do you consider the percentages of people who speak various languages in the world or would you say Spanish because Mexico is our neighbors?

Chinese, Mandarin 13.69%, Hindi 2.82%, English 4.84%, Spanish 5.05%, Bengali 2.68%, Portuguese 2.77%, Russian 2.27%, Japanese 1.99%, German, Standard 1.49%, Chinese, Wu 1.21% (2004)
