RE: "In addition the listeners need to be qualified, trained and their qualification and training proven."

This is part of the test protocol. If you are trying to prove that something can not be detected you have to calibrate the apparatus, which in this case includes the test subjects. This is well known by qualified scientists. The calibration and qualification processes become part of the experimental results and affect the conclusions drawn by the experimenter after reducing the experimental data. If a paper goes into a peer reviewed journal the referees are the ones to do any "certification". Or the readers after the paper has been published, if they are so inclined.
