Also, the majority of modern TVs have excruciatingly bad sound quality — an inherent byproduct of frame-less flat-screen TVs.
The most common sound issues amongst the kess good stuff I find are excessive dynamic range (for domestic environment) — which includes the mumbling actors problem — and music being too intrusive. I've shared my views on the reasons for these often before.
Both of these issues inherently make comprehension worse for older people with naturally degraded hearing, of course, and both have been hot topics of complaint in Radio Times since long before the day I first stepped through the BBC's door in 1982.
I wonder what that tells us?
