The problems with mumbling on TV start with the actors/actresses having poor diction, this is then compounded by poorly trained sound technicians and also possibly not very good equipment, then there is the point that nobody watches these programmes before transmission. To blame flat screen TVs is utter rubbish as all my old dvd’s, colour as well as black and white are perfectly audible at all frequencies. Proof – just watch Laurence Olivier in Henry V, sound is perfect in fact just about any film made before about 2000. Old time sound technicians cut their teeth in theatre where sound was even more important.
