I don't think that you will like my answer but I hope that the information provided will help you make some decisions.

Soundproofing is a very complex process and the biggest problem is that sound can travel in all sorts of ways. In your case the sound could be traveling through the floor/ceiling by air passages, the structure of the floor, reverberations in the floor structure, ducts and so on. The problem may also be the result of the acoustics inside the unit above you. Some of the sound may also be coming from the windows in the unit above you and your windows. I could go on.

A common and sometimes successful method to deal with this type of a problem is to carpet the floors in the unit above yours. Such a carpet must be installed on a properly prepared underlayment and must include a good quality pad. The advantage of such an approach is that it can help with the acoustics inside the unit itself and with the sound transmision through the floor. But here, as in all of the other potential methods of sound mitigation, the "devil is in the details". For example, if you don't take care of the old sqeaking floorboards the those floorboards will continue to squeak not matter what you place on top of them.

Another common but less successful method is the installation of a sound barrier in your ceiling. For example, you might install RC channel, insulation and new drywall on your ceiling or install a special suspended ceiling.

If you do decide to proceed with any of these methods, please make sure that the work is properly designed and properly installed. Even then, I would not expect miracles.

You may also want to become a bit of an expert in the field before investing more money n this project. Our reprint of Quieting: A Practical Guide to Noise Control may help. If you do order it, please remind me that you used The Express Service and I will give you a $3.00 discount on the order.

Are there other options? Yes, but you may not like those either: earplugs, white noise machines, moving your bed to another room, or moving to another apartment (with who knows what kinds of new problems).

I keep seeing and hearing about failed attempts to mitigate sound. The problems are almost always in the preliminary analysis and in the details. One thing is sure, there are not magic answers.
