Dr. Diamond vs high rez not better than CD
Posted by dave789 on July 4, 2012 at 22:41:02:
I heard two contradicting claims about 44.1kHz/16bit audio. What do you think?
Dr. Diamond, who is doing research on music therapy, claims that 44.1kHz/16bit audio has the opposite effect of soothing effect.
In a TV program in Asia, Dr. Diamond tested muscle strength of a person while she/he was hearing the same music of different format: live music, LP, SACD, CD.
Muscle strength was weaker while listening to CD.
The people in the experiment were the TV program producer, camera man, and a guide (probably for English translation) for the Asian TV program team.
So human being seems to subconsciously distinguish CD from higher rez digital (SACD) or analogue (LP).
On the other hand, there was recently an ASE paper showing that people including audiophiles could not tell the difference in blind test between high rez digital and high rez digital with 44.1kHz/16bit AD and DA conversions inserted in the playback chain.
