Homework Help: Why Do I hear bat cry?

    1. The problem statement, all variables and given/known data
    I downloaded wave files of bat cry. I played it on computer And I was able to hear it?
    Shouldn't that be ultrasonic??

    Here is the sample

    How do you think you are able to hear it? What could they have done to the sound to make you able to hear it?

    Did some tempered it? re-modulate it on lower frequency so we could hear it?
