Soundscapes of the Sonoran desert as a way to monitor environmental changes
The concept of Soundscape has gained gear in the last 20 years, based on today cheaper recording material and increased computational power in order to process the data. But if important advances have been made in the detection of certain animal species or group of species through this technique, the use of sound recordings in order to gain a more general idea of the state of the environment and its evolution in a specific region is less evident. The presentation shows an experiment in this direction. Using hundreds of hours of recordings in 8 places across the Tucson metropolitan area, we show how the use of specific metrics and indices allow us to map the diurnal and seasonal evolution of these soundscapes and how this gives a different sense of the geography than what we get with visual landscapes. These results are the first steps towards a more ambitious project of detecting soundscape changes and link them with local and global environmental changes.
