Silent Night? by J. D. Pye
Institute of Laryngology and OtelOKy, University of London
Many people have heard bats speak and know that they use ultrasonics to find their way about.

Dr. Pye talks about recording and analysing these sounds and studying the physiology of the bat's curious face and ears.
