Doppler with free fall bluetooth speaker?
Sine Wave A- 440 Hz Concert Pitch for Ten Hours - Test Tone

Played it on a standard HP laptop.

And I was shaking an old Galaxy III phone with 120 bpm (used a metronome before measurement to get the right tempo) maybe half a meter from the laptop (direction was towards and from the laptop, with phone microphone facing laptop). It was quite silent in the room.

Best regards.
