(1) Sound transmission class ratings of buildingassemblies shall conform to Section 5.9.
In Plain Language
Sound transmission class ratings between suites and other spaces in a building must meet the acoustic performance requirements set out in Section 5.9, addressing noise privacy between neighbours rather than fire or life safety.
