RE: Incidental sounds and notes fade into oblivion in audio faster than the prolonged images in video do.

.., and in video stores you often have several sets of screens playing at once. So it can be relatively easy to compare video screen quality amongst competition.

In the showroom, the screens are all in torch mode, which is not representative of home viewing. Without calibrating them all to the same standard, you might think one screen looks better because the apparent contrast or color saturation is a little greater on one screen in their default settings. Lighting conditions might vary a little from one spot in the store to the other. And they're usually looping demos that aren't stressing.

Picking a TV based on how it looked in the store is basically the same as picking an audio system based on how it sounded in the store. Both are expressions of preference based on observations that weren't made under controlled conditions. And that's about the best we consumers can do without a lot of effort.


But in audio, we generally listen to only one set of speakers playing one music recording at a time. Switching back and forth between speaker systems in audio, we are forced to rely on delayed memories that might be unreliable in comparative testing.

The main difference is how long it takes too switch between screens vs. how long it takes to switch between speakers, or whatever else in the audio chain you're comparing. If you use a switch box, you can go back and forth as quickly as you can step from one display to the next in the store. But a switch box might not make sense depending on what you're trying to compare e.g. cables. If you don't have a switch box, it could take a few minutes between changes, which makes it an aural memory challenge as you highlighted.

In general, I don't see why blind testing methodologies would be any less suited to video than audio, or vice versa.
