Seems like a minor thing.
I like the symbolism of the priest facing the cross. But it would be easier for parishioners to understand him if they can see his face. Especially hard of hearing.
Maybe a compromise? Have the priest face the cross but have a video camera on the priests face blown up for the parishioners to see.
when I was growing up there was a mike there
Get a copy of the 1962 version of the Missal of the Roman Rite and you’ll be abke to follow right along with an SSPX priest saying mass Ad Orientem.
Even without the use of electronic devices, I have never had trouble hearing and understanding the Priest when he is facing the Altar and Tabernacle. Most (first-world) parishes today, even with the Priest facing the congregation (and turning his back on the Tabernacle ...) use electronic amplification ... In practice, hearing the Priest isn’t a problem.
The Priest turns toward the people when they need to hear him during the Mass.
