What Sounds Do Bats Make?
“Hello I’m Dr. Christine Portfors. I’m an associate professor in the school of biological sciences at Washington State University in Vancouver. Today we are here to talk about what sounds do bats make. Bats make a lot of different sounds. The most well known sounds that they make are called their echo location sounds. And these are the sounds that we actually don’t hear most of them. Because the sounds are much higher in frequency then what the human ear can actually hear. So the bats use these sounds when they are flying around, they emit a very high frequency sound out of their mouth or some species emit it out of their nose.
