Peter,
No, ultrasound would not turn up on any video as the microphones only go up to about 10 kHz. Lower harmonics are doubtful due to the lead shielding. Some few people are annoyed by ultrasound, and can tell if it is present - even if they cannot exactly 'hear' it. From: Peter Gluck Subject: Re: [Vo]:Is there a "SONO" connection to the Rossi Demo? I will ask Daniele who was there. We have the registration of the demo, do you think the ultra-sound component got lost if it were there?
