I agree with your point in respect to the over-emphasis of particular leaning styles in the classroom.
At the same time the oscilloscope example is intriguing, since I could easily imagine research scientists using FFT, and wavelet decomposition to classify bird-calls as primary research. So I wonder if there is anything intrinsically wrong with the idea of using an oscilloscope in the classroom at lower-levels as part of a teaching strategy?
Meanwhile drama classes might be trying to get students to mimic bird calls - which also seems like a valid learning experience.

You might show kids the output from such an instrument as a brief exhibit piece in explaining a more relatable scientific fact such a tool would allow us to discover, e.g. that birds can pick out their own chicks' cries from those of their fellow species kin, but that's teaching about the bird's sensitivity. Not developing the learner's ability to analyze that. You would not use an oscilloscope as a means to teach the sparrow's call from the blue jay's from the robin's from the jackdaw's.
