Here’s some insight into what controls the chirping sounds that crickets make. I’ve been intending to talk about this paper, which is interesting to me since I’ve been interested in bioacoustics for a while (though, in my case, more in perception than in production of sound). But Natasha Mhatre, the first (and corresponding) author, has saved me the time by summarising it very nicely herself, here. Go and read to learn about how size correlates with frequency of sound, in a variety of creatures, and how it breaks down in tree crickets (whose frequency changes with temperature). The original paper is here. Additional coverage is here.
