insect guide to making sound and staying alive
July 9, 2007

Emit narrow band high frequency sounds so as to limit any phase difference recognition useful for direction finding.
Use sounds that lack transients or amplitude modulation.
Make use of the resonance of a larger object so that your sound appears to come from a wider area.
Broadcast in short bursts of sound, with long intervals in between, to provide minimum information for impatient predators.
