Klingt zwar etwas komisch, aber genau so würde es klingen, wenn die Fledermäuse das Batman Theme singen würden.
Bats produce sounds that are not audible to human ears. First these ultrasounds were digitally reduced to frequencies that are audible. Then the different batsounds were assigned different keys on a keyboard. On this keyboard – the only real Bat-Organ – Ulrich Seidel played the Batman Theme (Neal Hefti, 1966). The video clip was compiled by Sándor Seuntjens using footage from Batman (film, 1966), Batman (animated television series, 1992-95), and National Geographic (natgeowild.com).
