The validation via the senses is actually demonstrated in the video. It is suggested to close the eyes and notice that what is actually being heard. Those who take this video as evidence that "the senses can't be trusted" will possibly miss that part.
I would add that the video reminded me of a conversation I mentioned in the audio chat last week. I got into a debate with a friend, a medical doctor no less, who stated bluntly "I don't trust my senses". I got a tad annoyed at the obvious fact that he was telling me this so was assuming I could hear him. But I chose to ask him more about what he meant. Turns out he defines the "senses" as the entire mechanism of sense data + mental construction. So when the mind creates an illusion as it does in the video, he would say "see, the senses create illusions".
This way of defining the senses is a common error and we need to be on top of it with clear distinctions between "sense data" and "mental constructions".
