Airflow was repeatadly initiated for an organ reed pipe (Oboe at 263 Hz). The velocity of the
reed was measured using a Polytec PSV-400 scanning laser Doppler vibrometer.
The video shows the velocity profile as the reed begins to oscillate and reaches its steady state.
The peak acceleration towards the end of the reed exceeds 40 km/s2, or 4000 g's, when it impacts the
shallot and snaps from negative to positive
