From: The Sound Produced by a Dripping Tap is Driven by Resonant Oscillations of an Entrapped Air Bubble
Airborne and underwater sound recorded when a 4.0 mm diameter drop impacted the surface at 1.29 ms−1. The upper and middle plots show the full airborne and underwater signals respectively. The lower plot shows an overlaid close-up of the decaying wave-packet. The red lines indicate the locations of the video frames shown in Fig. 3, with only frames 8, 9 and 10 being marked in the lower plot.
