If you want to make a LOT of noise, you're gonna have to resort to an apparatus to make such a noise. I'm not saying you should start a
jet engine in your living room, but a few small caliope pipes (bastards) and a slightly modified pressure cooker sitting on one of those propane turkey fryers (those put out > 100,000 btu/hr!) will put out a shriek of well over 170 dB at ten feet or so. It will be heard by birds in the next county.
The best thing for making a lot of noise in an apartment is to bolt a 1/2 hp electric motor to a table with a four ounce half moon counterweight on the shaft. You may want to fasten the table to the floor somehow as well. Basically, it's like having 10,000 cell phones on vibrate getting a call at once. Ever see those old football games with the vibrating tables? That's what the floor would be like! It'll tickle your ass crazy so watch it! :Q
