Best Sound Insulation?

Categories: Insulation

We have an exposed brick wall in a brownstone and we can hear perfectly the next door neighbors. We are decided to put sheetrock on the walls of the parlor floor. Any recommendation for sound insulation? Someone told me about Homasote, someone else about spray foam, Quiet Rock… Any experience? What is the best sound insulation material?
