Masonry construction - sounds like the right choice

The higher the STC rating, the better the assembly can block or reduce the transmission of sound across it. STC rating is intended for use with typical indoor noises such as speech and office sounds. Lightweight wall systems having the same or similar STC rating as masonry will not perform as well as masonry when subjected to low frequency noise.
