Strike 6. Can you point out the flaw in this paper?
It has been demonstrated that frequencies above the human threshold of hearing generate brain activity, so super tweeters with a decent source are indeed relevant.
This is cool, but I would not take this as a proof of much. From what I read, we cannot discriminate any ultrasonic frequencies, we can just detect presence of some. There have been a fair number of tests over the years of whether people could tell the difference of music recorded to 20KHz, and recorded to higher frequencies. No one can tell when the bandwidth is larger.
We don't have to agree on everything, or even anything, but keeping it respectful goes a long way. Thank you to those that are.
