Impact of listening fatigue , during ABX test. 2009-10-09 01:46:22 Hi ,I thought I could test how high bit rates could be useful for me,by doing an ABX test based on a sample rich on high pitched sound.Correct me if I'm wrong, but high bit rates help to preserve high frequencies.So I used a sample from the OST of game "sentinel return"from John Carpenter. I precise, because it's not an artificial samplegenerated by me, but a music that exists.In attachment , there's a lossless flac version,and one encoded at 128kps cbr (lame 3.98).I tried to make an ABX test with two samples (using ABX comparator from foobar), but I realized that listening to the sample again and again was a bit fatiguing for my ears. Anyway here are the questions that arise from this test.First are you experiencing listening fatigue like me with this sample,and can you ABX them easily ? I'm not sure if that's important, but I use headphones, and with relatively loud volume, compared to my normal level for regular listening.For the ones experiencing listening fatigue, how would you overcome this ?Personally, I try to make a big pause of 30 second at least before makinga decision at each step of ABX test , just listening at silence or quiet music. But that's not obvious.And finally , do you think that the impact of listening fatigue can be ignored during regular ABX tests ? I've done many times some ABX tests, getting successful results in the 4/5 first steps , and then getting errors. So either the ABX comparator from foobar, is not truly random,and I'm good at guessing the first steps, or I'm loosing my ability to focus on the differences because of listening fatigue or anything else (likedistracting background noise).
