I don't think this reference is relevant. The test was conducted in
January 2000. Codecs have improved since then. A LOT.

As for the rest of your post: I don't buy it at all. I really would like
to see one of the more knowledgeable posters chime in (Julf, probedb
etc.)

My laymen's take on this is as follows. Lossy audio compression will
introduce noise and distortion. The codec employs a psychoacoustic model
that tries to introduce only artifacts you cannot hear. To that end, it
makes use of spectral masking. If you introduce an artifact, say, at
900-920 Hz, but in that same frequency band, you have signal with a
level 25 dB higher, you probably cannot hear the artifact.

So what is the story you can tell which explains why somebody with
impaired hearing would be more capable of hearing the articaft down
there?

As an aside, this whole discussion seems a bit funny. Should we conclude
from your analysis that hearing impairment is why people should spend
$$$ on lossless audio streaming? (I know you didn't say precisely that,
I'm exaggerating.)
