00:00Listen to these two sounds and think about which one you like better.
00:12So if you preferred that second sound, then it turns out that you agree with the song sparrow,
00:17which is the animal that actually produced those songs that you heard.
00:21I'm Logan James, and in a recent study we wanted to know whether humans share the acoustic
00:26preferences that other animals have. So in order to do this, we collaborated with researchers at
00:31the University of Texas at Austin, as well as Yale and the University of Auckland, and we put together
00:37an online platform where participants could listen to two sounds and then tell us which one they liked
00:42more than the other. Then we could compare the preferences of the people in the study directly
00:46to the animals that produced these sounds from previous research. We found that overall we do
00:52actually share many acoustic preferences with other animals. As another example,
00:57you can listen to this call from a frog,
01:02and if you're like the frog and most participants in our study, you may have found that first call
01:07to be a little more interesting or a little more attractive than that second call. This call comes
01:12from the Tungura frog, which we studied down in Panama, and its call sounds, we call it a whine,
01:17followed by multiple chucks. And that first call had more chucks than that second call,
01:23and for some reason we all find that more chucks makes the call sound a little bit better.
