Ways to Reduce Atmospheric Noise

Hi Folks,
My tinnitus is coming back as a result of a cold and I believe also, due to a hyper-sensitivity towards atmospheric noise. The primary culprit is my annoying refrigerator which is up against a corner. I live in an apartment and I have my audio components in the best possible location but its relatively close to the kitchen. I also have neighbors above me who make a good deal of noise, primarily floor squeaking. Should I try placing noise proof styrofoam along walls and ceilings with velcro? Advice sincerely welcome!
Frig get felt (or small area rugs) and stickies.. Add velcro stickies to felt/rug and wall. places around sides and back of wall around frig.
Then perhaps aquire a folding screen, and place in front of frig when listening?
Also perhaps some antivibration mats to place under frig feet?

The squeeky floors needs the owner or caretaker to stick a few finishing nails into the subflooring. (best at an angle) where the floors are squeeking.
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.
Some hardware stores sell tiles about 2 feet on a side....usually in 4 packs.
The tiles link together. I use 'em in front of my workbench and have one for yardwork, as a kneeler. They are about and inch thick, hard foam.
Refrigerators do need some space between surrounding areas to operate effectively.
At first glance I thought this post was about cosmic rays and shielding with foil hats, but to my surprise and immediate realization, I have a noisey frige too! So thank you, and I am gonna get some material as well to isolate the darn thing.
changing the power cord on the fridge to more warmer one....
buy a new fridge , new ones on the market are almost silent (probably cost less than cable upgrade)...
I bought a new fridge last year to replace a 20 year old GE.

New fridge is enough quieter to make a difference and runs FAR LESS which is worth about 50 KwH per month reduction vs the old electric bill. The reduction works out to missing about 6 weeks worth of bill per year. A win-win

The fridge with the IEC cord was about 200$ more, and was a no-go.
Yes, I would buy a new refrigerator if I could afford to do so but I am saving for a good mono cartridge and the refrigerator came with the apartment. Fortunately I don't own a dishwasher or the noise levels would be twice as frustrating. I'm planning to visit ACE Hardware for a mat to fit under the refrigerator. Lastly, I'm wondering if velcro fastening styrofoam or something else along the ceiling wouldn't dampen the squeaky floor above me? Pleading for the landlord to hammer finishing nails along the noisy floor boards would just be futile.
