I know I can get the visible absorption spectrum of water <https://en.wikipedia.org/wiki/Water_absorption> But how does one go about getting and testing what the absorption spectrum is for a glass of water in the audio range of (0hz to 20000hz) I know nasa uses water to absorb sound <https://youtu.be/08aHEmuzMLI>.
How can I measure what the sound absorption spectrum is in a glass of water?
