Best Blocking (STC 50) – Full Height Walls (Preferred)

A sound blocking level of STC 50 means that a listener in a quiet room would need to exert effort to hear raised speech levels in adjacent rooms, and the speech would not be understandable or disruptive. Acoustic standards, guidelines and building rating systems require a STC 50 rating between rooms such as classrooms1, conference rooms 2, 3, executive offices2, patient exam rooms, treatment rooms and consultation rooms4.
