EAR TONES

That Japan university Web site appears to be operational only some of the time. One of the reasons that I posted a note about the site is because I believe that the people running it may have already done some or perhaps much of the research needed to explain how “Ear Tones” are being generated. And people interested in that subject matter could try contacting them in order to learn what they know rather than forever wonder what the source of their Ear Tones might be.
