User note:

About this appendx: Sound transmission relates directly to the psychological and long-term physical well-being of building occupants. Many human activities cannot be accommodated efficiently or comfortably in various types of building spaces without proper attention to the mitiga- tion of sound transmission from other spaces within the building, or from outside of the building. In Appendix K, attention is specifically paid to the mitigation of sound transmission between dwelling units and other dwelling units and occupancies.
