hearing tests - where and how?

Kal, not sure where you got that - the subject has been researched for decades by many different people in many different countries, along with much other brain research. A Google search should yield more info than anyone would ever really care to know on the subject. Much of the knowledge was discovered quite accidentally when researchers were studying the brains of people who were deaf. There is also alot of fascinating research out there about how the brain perceives spatial distances/relationships, much of which is actually received through the ear rather than the eye, again even in deaf people. I came across some of it while researching a paper I had to write back in my college days for an acoustics course. Don't have any of those notes anymore, that was over twenty years ago now, but I know the info is out there.

From many years as a neuroscientist who studies and lectures on the topic. When there is reliable, confirmed and replicated evidence, let me know.

Hi Kal - so apparently the research I read about back then has been called into question in the last twenty years at some point? If so, this is honestly the first I have ever heard of it - as I said, I remember it being discussed in multiple studies not as a theory, but as scientifically proven fact. Perhaps they were indeed based on the same original research, but I don't remember it that way. Certainly there are many people in the audio/music industry that believe it. I would be interested in hearing how this was disproven then, if it has been? Or was the research merely deemed unreliable by someone, which is what you seem to be implying, and if so why, if this is easily put in layman's terms? I am certainly no scientist, but the idea does seem to make sense, even if it hasn't actually been proven reliably. Please feel free to send me an email through the audiogon system if that's easier.

I have tested the hearing of thousands of people and many of them will respond to a tone physically via things like head movement, eye movement and/or a puzzled look on their face exactly when the tone occurs yet won't raise their hand to conform they consciously hear it. At a subconscious level (it certainly seems)they are hearing it but they cannot consciously react and confirm it. This condition I describe above where you see a physical reaction but the person being tested does not respond by raising their hand always occurs within 5 or 10db of their actual conscious threshold where they do raise their hand.
