I normally listen on FM of course, but yesterday I checked on the bit rate
on Radio 4 yesterday morning and it was 128 kbps. Noticeably inferior to
FM.

FM doesn't have a "bit rate", so it's meaningless to say that 128kb/s is
"noticeably inferior" to it. Or perhaps you mean that the sound quality was "noticeably inferior"?,

Of course I did. It must have been obvious. what is a "scientific
listening test"? Is it what most people call "listening"?
