Excellent book by the artist and scientist "The Secret of the Turtle", section (page 377 and the following). It's about the turtle armor as a sound room and resonance body, which can also be found in musical instruments (drums, ocarinas, lyra etc.), see also my turtle lyra, built by Sebastiano Goio and Marion Michael (violin builder).
