This is a spectrogram of a synthesized soundscape of sounds that cannot be heard by humans without the use of technology. The Y axis is frequency and the X axis is time. This soundscape includes ultrasonic sounds (above the range of human hearing, played back at lower frequency), substrate-borne vibrations, and otherwise very quiet sounds.
All sounds recorded by Lisa Schonberg on Pipeline Road in Gamboa, Panama in August 2019 at the Dinacon Digital Naturalism Conference (with the exception of one recording of a wasp nest, recorded in the town of Gamboa in a field). Composed and edited by Lisa Schonberg.
Sounds featured, in rough order of appearance:
1. Ultrasonic component of dawn soundscape on Pipeline Road
2. Paper wasp nest on cecropia branch, through substrate
3. Atta (leaf-cutter ant) foraging trail, locomotion sounds
4. Azteca ants on Cecropia tree, locomotion sounds
5. Cicada, ultrasonic component
6. Odontomachus (trap-jaw) ant, stridulation (partially ultrasonic)
7. Labidus (army ant) trail, sounds of locomotion and aggressive behavior
8. Ultrasonic component of dusk soundscape, from canopy, Pipeline Road
