Large Drop Animation
	How do Raindrops Make Sound Underwater?		For large (2.0-3.5 mm diameter) and very large (greater than 3.5 mm) raindrops, the splash becomes energetic enough that a wide range of bubble sizes are trapped underwater during the splash, producing a loud sound that includes relatively low frequencies (1 - 10 kHz) from the larger bubbles. For very large raindrops, the splat of the impact is also very loud with the sound spread over a wide frequency range (1-50 kHz).
