Hi Bob:

Just thought I would ask a few Q's:

1) What was the source of the audio waves? A piezocrystal excited by a waveform generator which physically pressed the crystal?

2) Did you try to isolate audio from electromagnetic effects (i.e. shield from EM but allow acoustic waves only)?

3) What waveform was used (sine, square, triangle, etc.)?

4) Did u actually measure the emitted spectrum?

5) Did you use a shielded room (to keep out noise signals)?

6) Was somebody jockying the waveform frequency to see if the people could track up or down or was this discerned by measuring the output and then comparing hand-signals?

7) for "audion wave" did you mean "audio wave"?

8) If you were meauring the actual waveforms produced (?) what was the upper -3 Db (half-power)cut-off frequency (or sample rate)?

9) Was only one or the other "ear" involved in "hearing" or was the single ear experience replicated ?

A busy body,
