In Reply to: There is no question that laboratory measuring devices are far more sensitive and accurate than our hearing... posted by McCormack on February 14, 2007 at 15:19:06:
Frequency response.Human ear? 40-19khz (teen) 40-16khz (middle aged adult).
(Yet we have audiophiles getting headaches from RADIO FREQUENCY INTERFERENCE!!!)
Test instruments? DC to light.
Sorry. Test equipment rules there.
Another nice thing about test instruments is that they don't rely on PERCEPTION.
Oh, by the way, the "measureability versus audibility" debate still goes on. You can't just say "ears won".
We'll you can. But you would need to refer to a universally accepted CONTEST that was held. There is a lot of talk on the subject but very few references to work done by auditory experts and authorities in the field of human hearing.
I think it is still largely debatable whether or not audiophiles actually DO (or CAN) hear differences that are (or would HAVE to be) below our current measuring capabilitites. One thing is for certain, if you PRETEND that you change a cable, you REALLY start getting reports that something changed. Now, how can we, in the face of this AMAZING evidence of the powers (and failings) of human PERCEPTION, even COMPARE our auditory systems to a calibrated instrument?
Theory not bought.
If this were true, manufacturers would HAVE no instruments. Just a bunch of middle aged guys locked in a closet and brought out whenever "critical listening" tests.
Anomalies in frequency response can be measured down to 0.1 db with cheap equipment.
Humans can only PERCEIVE changes of 3db or MAYBE 1db for an exceptionally trained ear.
Cheers,
Presto
