View source for Reverberation Time (RT60) and Sound Masking Performance 47809

When people talk about sound masking, they usually focus on volume and speaker placement. That is necessary, but it is not the whole story. In the rooms where masking actually works, the sound does not behave like a neatly controlled broadcast. It behaves like acoustics, reflections, and decay curves fighting for dominance. That is where RT60 comes in.
