Soundscape ecology
Soundscape ecology is the study of sound within a landscape and its effect on organisms. Sounds may be generated by organisms (biophony), by the physical environment (geophony), or by humans (anthrophony). Soundscape ecologists seek to understand how these different sound sources interact across spatial scales and through time. Variation in soundscapes may have wide-ranging ecological effects as organisms often obtain information from environmental sounds. Soundscape ecologists use recording devices, audio tools, and elements of traditional ecological analyses to study soundscape structure. Increasingly, anthrophony, sometimes referred to in older, more archaic terminology as anthropogenic noise dominates soundscapes, and this type of noise pollution or disturbance has a negative impact on a wide range of organisms. The preservation of natural soundscapes is now a recognized conservation goal.
