I am guessing that the spectrum of droplet sizes grows with height, adding a 'big squish' sound for high falls. This could be tested in a lab. | |
| Jan 7, 2013 at 20:26 | comment | added | Mark Rovetta | Thanks for your attention. Yes, there may be no characteristic acoustic feature that changes continuously with height. But I expect there might be transitions one might discover going from the low-energy to high-energy environments. Gravity is about the same everywhere on earth, so the sound of high falls might include a distinct signal (cavitation?) absent at low falls - its seems a question worth asking a broad audience. | |
