Technical and scientific discussion of amps, cables and other topics.

Re: No…

There is another aspect to this. It is quite possible that the audible effects of the ultrasonic signals were due to intermodulation effects which were in the audible range.

This was the conclusion of Ashihara Kaoru and Kiryu Shogu in AES Convention Paper 5401 presented at the 100th Convention may 12-15, 2001. In other words, when they played the signals over the same loudspeaker, people could hear the difference, but when the signals in the audible range and the ultrasonic range were played over separate drivers, they could not.
