Speaker Bernie Krause's sound examining keynote discusses what nature recordings can teach people about wildlife and changes in habitat. Krause has been creating nature recordings for decades and has noticed some significant changes in these habitats in terms of sound.
Krause claims that studying these recordings makes it clear that global warming, human noise and resource extraction has had a harmful impact on these ecosystems. He says that habitat recordings can serve as helpful tools for evaluating the health of a particular ecosystem. By comparing old and new recordings from an area, one can hear a significant difference that reflect the changes in an area.
Krause explains the value of soundscaping. He claims that animals express themselves through sound and examining wildlife recordings can help experts uncover irregularities or harmful habitat changes.
