Effects of aircraft flyover on biophony
Soundscape ecology emphasises the ecological properties of sound and its spatio-temporal patterns when it emerges from landscapes. Any soundscape consists of a characteristic mixture of biophony (sounds produced by non-human animals), geophony (sounds produced by the abiotic environment) and anthrophony (sounds made by humans).
The ecological soundscape consists of all sounds produced by humans (anthrophony), non-human animals (biophony) and the abiotic environment (geophony). And soundscape ecology can shed light on biodiversity-wide impacts of human activities based on the acoustic niche hypothesis – the idea that animals partition themselves into acoustic niches to avoid masking. In general, we can expect that as human activities degrade habitat quality, e.g., via disturbance, the density and diversity of sounds in different bandwidths of the biophony may decline.
