August 12, 2021 – With the coming of the Fall 2021 Semester, University of Maryland (College Park) prepares for the cautious return to in-person classes as the pandemic continues.  The increasing spread of the delta-variant of the COVID19 has brought back the indoor masking requirement so it appears (unless things change soon), that we will be teaching with masks on.  How will this work?  Will we be able to have students discussing problems in groups in the classroom like the ‘before times’ ?   Amplified mask microphones?   Darth Vader voice processing?
