How does one detect ultrasonic oscillations?
With an ultraoscilloscope, of course. Actually, any oscilloscope worth
a hoot will display waveforms up to 500 kHz which, other than in
exceptional cases, is all you need to worry about. You can still find 50
year old Hewlett-Packard scopes for under $25, and you can learn a lot
about audio (and about oscilloscopes) with one.
