I am very happy to have recently discovered HA. Especially after some long discussions with friends of mine who insisted that they can hear a difference between FLAC and a high quality MP3, but were not willing to perform a simple blind test. It's a pleasure to see that so much effort is put here into objective blind listening tests.

However, I am surprised to find so little academic research on in this subject. The problem with most ABX tests on this forum is that the number of participants is generally limited and that you are dependent on the equipment of the participants. I find it strange that I can't find any academic research into this subject. I would love to see a test involving a large number of participants, a fixed set of (high quality) audio equipment and proper statistical analysis. With a large number of participants also factors like age (with their differing audible frequency range) could be investigated.

Considering that many codecs originate from academic institutes (i.e. Fraunhofer etc.) I expected that there would be a large number of scientific experiments on the performance of different codecs. However, I cannot find any of them. Am I perhaps looking in the wrong direction?

We have all been there.

I think that the tests carried out by Floyd Toole in the 80s are good examples of how it can be done (loudspeakers in small rooms). The ideal test depends on what it is that you want to know. Do you want to figure out what the general public is able to distinguish? Do you want to estimate an upper bound to what 1/1000 or 1/100000 of the population are able to distinguish? Or do you want to know what you yourself is able to distinguish?
