> it also could just have a lot to do with the fact that, well, they have tiny articulators and tiny vocalizations!
Now I'm imagining some alien shrew with vocal-cords (or syrinx, or whatever) that runs the entire length of its body, just so that it can emit lower-frequency noises for some reason.
Sounds like an antenna, if you'll accept electromagnetic noise then there are some fish that could pass for your shrew, e.g. https://en.wikipedia.org/wiki/Gymnotus
Was playing around with a fundamental frequency calculator [0] to associate certain sizes to hertz, then using a tone-generator [1] to get a subjective idea of what it'd sound like.
Though of course, nature has plenty of other tricks, like how Koalas can go down to ~27hz. [2]
I’m not sure exactly how, but cats can emit a surprisingly low growl when they want to. Like, as deep as a large human would be able to. So there’s more going on than just linear size… And how I’m wondering what the lowest recorded pitch made by a shrew is.
