190.0. "Relative sound levels" by GRAFIX::CHALTAS () Sun Oct 06 1985 22:15

Well, I finally bought a CD player (Yamaha CD-X2 , $280 at Tweeter (asking
$300, but there was a scratch on top of the case)).  I'm pleased with what

I got -- please don't send "Oh you fool! you should have got (or paid)..."
mail, but I've noticed a curious phenomenon.  I always set the volume
control on my amp signficantly higher with the cd than with discs or cassettes.
So does my wife.  I have A Nakamichi 480 cassette, and a Rotel,RA840-B amp,
if it matters, and almost never turn the volume control above "4" when
playing tapes (or vinyl discs).  With the CD I usally turn it to "5" before
I feel that the sound is sufficiently loud. I'm wondering if this is because
a).  The Yamaha CD player has a lower-than-normal output level.
b).  The greater range of CD's means that I have to turn the gain up more
     to hear the quiet parts and the cleaner sound means that I don't object
     to the higher sound level.
c). ???
                              
Has anyone else noticed a similar phenomenon?  Any thoughts as to why?

I've noticed the same thing, so I don't think it's your particular disc player.
I attribute it to the dynamic range, but I don't have any scientific findings
to back that up; it's just what I mumble to myself as I turn up the gain.
Since I set the volume for the "usual" sound level, and I note that the loud
sections are louder than I would nomally listen to, the range explanation
seemed reasonable to me.

I would concur.
190.3ORPHAN::MEIERMon Oct 07 1985 15:586
I have also read somewhere, that because of the cleaner sound you tend to
turn up the volume a little more. Also, as it says on some of the CD's
something to the effect of "turn the volume up and you will here new
sounds and greater dimension and depth, etc etc". Again, probably related
to the increased dynamic range as well.

190.4EIFFEL::LIONELMon Oct 07 1985 21:115
What complex explanations!  I think it's more that the output level of the
CD player is lower than what the receiver expects as a "standard" line
input.  That's why more expensive CD players (and cassette decks, etc.) have
line output level controls.

I believe that it is a combination of both explanations. That is because
the dynamic range is greater and the output should be limited to prevent
overdriving the line input of the next stage, the "average" must be set
lower in the CD player! I have certainly noticed the affect and agree
also with the improved "tolerance" of higher levels do to the purity of
CD output.

Well, I think the whole thing can be attributed to perturbations in the energy
fields of the music waves caused by the combined psyches of the ancient
astronauts, but then, I could be wrong.

re .4 regarding line output level controls...

My husband got into an argument with a salesman at Tweeter in the Mall of
NH about line output level controls.  We were asking if one of the Yamaha
CD players had one and the salesman said that he couldn't imagine why anyone
would want one and that we were pretty stupid for wanting such a thing.

Needless to say we didn't buy a CD player there.
(Although we did buy one from the Tweeter in Nashua.)

re .0
I noticed shortly after we got our CD player that I was playing CDs at a
louder volume than I play records or cassettes because I found I had to shout
over the music if I wanted to talk to someone when I was playing a CD.

I assumed that the reason that I listen to CDs at a louder volume was due
to the lack of background noise and distortion.

I too noticed that I tended to turn up the volume more, which may be related
to another phenomenon.  One of the "analog-phile's" arguments against CD's
was that listening to CD's caused headaches after a while. I noticed this
too; after a few hours of listening I would sometimes get "audio fatigue"
or whatever you want to call it.  I believe this was actually caused by
the higher than usual sound levels, and not the "distortion" as claimed by
the anti-CD elements. I guess that great S/N ratio tempts me to turn
Mahler up to something like 0.8 or 0.9 Soltis (for those of you who don't
know, a "solti" is the prefered unit of sound volume when refering to
Mahler  :-)   )

Re: .8

OK.  I'll bite.  Why is a "solti" the prefered unit of sound volume when
refering to Mahler?

The unit "solti" is named after (sir) Georg Solti, a Hungarian expatriate
and for many years (and still) the Music Director of the Chicago Symphony
Orchestra.  He is famous for his Mahler (as well as other things).  I 
prefer his recordings without the CSO, but it's a matter of personal taste,
not quality.
