Do you have wood floors? 

Is the complaint about impact noise (thumping from footsteps) or airborne noise (talking, TV, stereo, etc.)??

Since you have carpet and pad, impact noise is probably not a big problem.  Unfortunately, it sounds like you live in a building that was built before the noise requirements were enforced for multifamily dwellings.   Your downstairs neighbor's ceiling is attached right to your floor joists, with no insulation to speak of, and no sealing of any kind.  The problem can best be addressed from downstairs, but you could remove the carpet and replace the pad with MLV + 1/4" closed-cell foam.  It runs a couple bucks/sq.ft, but it's a lot more effective at blocking sound than your flimsy carpet pad.

If you do a quality installation job (ask SSP for instructions) you can get good results.

I have more question..~~

1. Can you estimate cost to install above MLV material approximately ?
    My livingroom is about 500 Sq Ft . 
    I know material cost but I can't estimate labor charge if people from this site install it.

2. Is it possible for me to install by myself technically ?


Thank you very much.

Yes, either you or your carpet installer can easily install the SSP Mass Loaded Vinyl with Closed Cell Foam Backing. The roll is 4-1/2' wide x 25 foot long. It weighs about 140 pounds per roll. Install the roll with the foam down touching the floor. Butt seam only - no overlapping. Tape any seams. Then have carpet installer nail down their tack strips around the perimeter and lay down their re-bond rubber carpet pad and the carpeting of your choice. This combination will greatly reduce air bourne sonds in both directions.

Would the same recommendations apply for hard wood floors?  I don't feel any vibrations, but I can hear my neighbor coughing and hacking.  I can also smell anthing that my neighbor is cooking.

This would work if you're going to have carpet put in over your wood floors, otherwise the barrier would need to go under your wood floor and you would use Mass Loaded vinyl and SSP-FL underlayments. Here are the links to these materials.

Dang it.  I sure wish that I had know about these products before I had the hardwood floors installed.

For blocking air-borne sound only from the neighbor below you can also use 1lb/sq ft MLV with 1/4" Open cell foam.  If impact noise is not an issue.  It goes with the open cell foam side down to insure full sound barrier effectiveness of the MLV.  Carpet pad and carpet then install on top.  It is the "Better" type discribed at                        http://www.soundproofing.org/infopages/flooring.htm
Installation is similar to MLV w/closed cell.
