I want to add additional walls to a room in New York City to block the sound - from the other appts in that manner. www.soundproofingcompany.com/soundproofing-solutions/soundproof-walls/spc-solution-1-green-glue-wallFiberglass , green glue , dry wall I will not do anything to the already existing wall .Do I have to use fire rated wooden beams ? Anyone has any info about that ? Are there any building codes requirements ? From what I understand trying to navigate in the NYC building code I don’t have to since it is not a supporting ( bearing wall ) But I cannot be sure .. Any ideas ? Another concern a friend of mine has about this project : he thinks that a lot of sound travels under the walls and also conducts via shared subflooring that runs under curtain walls is there a possibility that I could still hear sounds from other appts even if I build this wall?

I'm not a sound proofing authority but I'll guess that, yes, you'll still be able to hear things. You'll probably get some benefit since you're adding absorption but usually the approach is to isolate completely including the foundation.

The site you linked gives good basic info. Keep in mind this can be rather expensive and it's unfortunately easy to end up with inferior or less than desired results.
"Soundproofing" is a misnomer. It is virtually impossible to eliminate all sound from entering or leaving a room. "Sound transmission attenuation" is a more accurate description.
This is a completely separate and extensively detailed subject than acoustic treatment. I'm not an authority either but I have looked into this and done some builds in the past.
Another question you have is building codes. Check with your city. I know different municipalities have potentially differing codes but I'll guess you may be required to use steel studs instead of wood.
Rod Gervais' book is a good resource. In short your wall should consist of three parts: Mass - Air - Mass. Flanking, another issue, is when sound goes around your "soundproof" wall so if you really want maximum sound attenuation, you probably need to build vibration isolated walls plus ceiling and floor; essentially a "room in a room".
There are a few threads here where I go into greater details I have learned so you might search this forum but better, check out Rod's book. Keep in mind that this in not absolute but more a question of "How much sound attenuation do you need?"
