Conclusions
A wide range of analytical techniques can be used to understand intricate ani-
mal sounds. We can use high-speed video and slow-motion replay to follow
beating wing patterns, microscopy to look at their anatomy, as well as the
usual spectral and time analysis of waveforms. Each has a unique and special
way of making its call.

Exercises
Exercise 1
Imagine you have been given the task of designing an outdoor scene for a par-
ticular location and time. Research the creatures you would expect to find in
that setting. Locate recordings or studies of the insect calls and implement
some of them as closely as you can.
Exercise 2
Emulate the katydid (Pterophylla), common in the Americas and Canada. How
do you think it makes the changes in resonance that give a chattering sound?
Exercise 3
Insects’ calls have meaning. They are like radio transmitters and receivers,
highly tuned to one another’s sounds. Make a pair of insects that communi-
cate. When one calls, the other responds. Place them in a stereo field so that
you hear them calling across to each other.
