I know many of the regulars in this sub-forum already know this. Seems we regularly get people in the Sound Science forum who wish to dispute or question the need for matched listening levels, and claiming long term listening is more perceptive.
A short video by Bob Katz at the AES talking about effects of loudness and loudness war. Bob Katz' comments that might be easily grasped in how slight loudness increases sound so much better to us.
The other deals with the accuracy of our perceptual memory. This one is probably the more important. I find convincing people levels need to be matched is easier to do. The benefit too keeping comparison intervals short is a much tougher idea to get across. This is a recent article on testing done of aural, visual and tactile memory. Results indicate aural memory degrades faster than the other two senses. Being only a bit over 60% after 32 seconds in the testing done here.
