[net.audio] on hearing and measurements

richard@aplvax.UUCP (07/08/83)

	Some peope think that if they can see it on an oscilloscope, or
measure it with some 'standard' test setup, they can hear it.  I don't.
Some people think that one component that measures 'better' than another
will sound 'better'.  I don't.

	The actual reproduction and perception of music is MUCH different
than the measuring of contrived signals with contrived (albeit 'standard')
test setups.  In my experience, attempts to correlate electronic measurements
with sound 'quality' are largely a failure.  While gross comparisons can be
valid (an amp that clips badly will almost (ALMOST) always sound worse than
one that doesn't), any CONCLUSIONS drawn from test measurements are likely
invalid.

	No one today understands what measurements to make, or how to make
them, in order to characterize the performance of a system reproducing 
music.  Further, in my opinion individual hearing differences and room
acoustics make all but the MOST GROSS characteristics of music reproduction
UNMEASURABLE!!

	What do you think?
