Electrical measurements are great in that they have excellent repeatability and reproducibility. They however, are a surrogate for human listening and perceptions. A surrogate where no in-silico to in-vivo correlation to listening to my knowledge has been reliablely established. Try getting a statin today approved with simply cholesterol measurements. You need to demonstrate efficacy and safety with hard endpoints (reduction in heart attacks etc.).
Are you saying that if there is absolutely no change in the electrical signal that is the sole producer of a phenomenon, it can still actually be changed by virtue of someone listening to it? Statistical methods cannot study or verify a physical phenomenon that cannot possibly exist in the physical world. Again, this is not about what someone thinks they hear. Discussion of audio equipment is not about hearing, it is about changes in the behavior of the equipment. No change, no difference to hear. If there is a change, then feel free to determine its audibility. This is not related to the interactions of substances with complex biological entities. This stuff is relatively easy to measure.
Outside the domains of quantum mechanics, some things ARE cut and dried. I imagine misapplied quantum theory will be the last refuge of snake oil purveyors.
