Actors generally don't use full voice in rehearsals, even dress rehearsals for plays. Musicals are slightly different. But the point is directors won't know how an actor intends to use his/her voice until the first performance in front of an audience and then it might be too late for remedial action, particularly if the actor that is too quiet is a highly-paid tv name. I suspect that Peter Hall is getting full volume from the fantastic Michelle Dockery in Pygmalion.
Thankyou for your reply but I must disagree. Being a trained and working actress myself I have had experience of differing modes of directing and to leave the discovery of how an actor or actress is going to use his or her voice on the performance night is enough to send shivers down the spines of voice coaches fellow actors and the poor unsuspecting audiences in theatres everywhere (with or without poor acoustics)
