Dear International Colleagues,
I believe you all are aware of the long standing dispute between the subjectivists and objectivists in Audio. I believe nothing new has been learned in these discussions for the last 30 years or so and they basically come down to the inability of people who hear sonic differences to prove this in an ABX-Test which is then often considered to be prove of the non-existence of sonic differences.
We are putting a new spin onto this by resorting to a different field. People who work with graphics have often seen colour charts that show minimal differences that are only apparent in comparison to the surrounding colours. If one was to identify an individual colour without the surrounding ones for comparison that would be mostly guess work.
In other words: Even though there is a subjective difference to the observers senses and an objective difference as the colours really are mixed differently that does mean it will always show in an ABX-Test. Thereby the claim that not passing an ABX-Test means that there is no real difference is void.
We have integrated this concept into a small flash program you can access at www.sieveking-sound.de/abx which will do a little test with you were you are asked to first make sure that you do see the difference between two colours and then have to identify them later on. I yet have to score perfect and more often than not my results would let some people claim that this was proove that there is no difference in the colours. Alas
