Does calculating new active receivers invalidate previous sound level results?
Calculating for newly “active” receivers invalidates previous active receivers’ results. If you run TNM with active receivers and then add more active receivers, TNM invalidates results for previously calculated ones when you try to calculate for newly activated ones. The exception is if you calculate “All” receivers the Calculate, Current Run, All Receivers command after calculating only some receivers using the Calculate, Current Run, Active Receivers command. In this case, you will get a message box asking if you want to recalculate the already-calculated receivers or if you want to skip recalculating those receivers with results.
