80 kbps LC AAC listening test Reply #25 – 2007-01-08 13:27:49 Quote from: SirChristof on 2007-01-08 13:07:14Doing very many ABX tests between them (assuming you hear a difference), better allows you to "rate" them. Without such attention to detail, the test becomes less meaningfull, at least in my opinion. ...If I did not do many ABX tests to first prepare myself to get accustomed to what I should be hearing, I could simply say 5/5 and move on. When people don't give a full effort, and just listen a couple times then determine "It is transparent", that severely waters down the results from people like me who actually did everything in their power to not only hear the difference, but rate it as honestly as they can.Your metodology for participating in listening test is meaningful and it would be really nice to have some test with people that are doing just like you described. But how many people would do that? IMO not many even if you pay them.In public listening test many people don't give as much effort as you. But this does not "water down" your results. Public listening test produce average scores (that is average scores among people interested in doing test which should extrapolate to whole population that listens music). Most people don't hear differences without full effort, but their grades also count.Also have in mind that in another time in another place in different circuimstances, you wouldn't give exactly the same grades People are just not accurate enough.In short: if you are deciding between 4.6 or 4.7, just give any of those.
