Ways to Reduce Atmospheric Noise

Thanks Elizabeth,
Primarily what I had anticipated but wasn't totally certain. The only difference is that I considered sheets of foam core and sound proof styrofoam being as it's light weight but now that you've mentioned it, so is felt. It looks as if I'll have to accept squeaking floors above me or otherwise move to a top floor apartment. If I mention this concern to my landlord he'll just shrug and tell me that its a frivolous issue. I would like to maximize the audio experience in this apartment by blocking out noise but by developing an acoustic environment as well. Is there a manufacturer who creates affordable but effective panels that might apply to my situation? Also, professional earplugs, could they at times be of help?

The noise generated by appliances such as a compressor in a refrigerator or the spray nozzle of a dishwasher resides well above the bass regions, and good old absorption and isolation is the key here. The first thing you should do, as suggested above, is mechanically isolate the refrigerator from the floor. Just as you would decouple your TT, you don't want the vibrations of the refrigerator to interact with the floor and walls translating into noise. Many times, this alone is enough to satisfy. If not, I would try free-standing absorption in your listening room with an air gap between the kitchen wall and the absoptive panels.

The creeking floor is the hardest... That would certainly require intervention and a mechanical fix from the landlord!

Yes, that totally explains the best approach to the problem in the kitchen. I'll opt first to place a floor mat of synthetic material under the refrigerator and then go from there. I'm also cogitating about placing free standing panels behind my electrostatic speakers. I like the acoustics in the gallery seating here in Cincinnati's Music Hall and while being in an apartment that's not exactly relevant to my situation , I'm nevertheless curious about what can acoustically be done to a room via artificial means.
