Although I have no real desire to dismiss the implication of prescience in
Cherie's comments ;-), my source (the liner notes for the CD I mentioned)
actually says that the BEST binaural beats occur around 400 Hz (but with
delta f's of about 30 Hz.) The "high" frequencies at which the beats
generally disappear are reputedly higher yet -- above 1500 Hz.
