Re: Are these biases?

"IF (note: big "if") you want to find out whether HF content can be perceived by listeners in some way (note: I did not say 'heard' for reasons I will state a little later), then I think as an initial test it is more than reasonable to start with subjects who are under 35 and largely female, and with music with a high HF content, because if you can't get a positive result under those circumstances you would seriously need to consider giving up on the hypothesis."

This is simply starting at one extreme of possibilities to give the "best case" set of conditions. I see nothing scientifically invalid at all with those and I am not sure why RBNG thinks these are biases.

It also seems to me that brain activity is a much better indicator of whether someone heard a difference than simply asking them, which can be full of bias. Involuntary responses are most likely more accurate indicators.

As to FM, I am not sure why RBNG decided to muddy the waters with this comment. Since no one has ever heard FM with content ABOVE 15Khz then who is to say whether people would like it better or worse than with that content? Most people prefer cd or lp to FM radio in a high res system, is this because of more HF content?? Who knows.
