No. This feature is not yet implemented in TNM. As a result, the columns, “Reflections ?”, and the associated next three columns are grayed out and not available for selection/editing. To see how some users have modeled sound being reflected off a single barrier, please refer to the FAQ in the Parallel Barrier section regarding single wall reflections.
