Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial. First appearing in the Handbook for Acoustic Ecology edited by Barry Truax, in 1978,^[1] the term has occasionally been used, sometimes interchangeably, with the term acoustic ecology. Soundscape ecologists also study the relationships between the three basic sources of sound that comprise the soundscape: those generated by organisms are referred to as the biophony; those from non-biological natural categories are classified as the geophony, and those produced by humans, the anthropophony.

Increasingly, soundscapes are dominated by a sub-set of anthropophony (sometimes referred to in older, more archaic terminology as "anthropogenic noise"), or technophony, the overwhelming presence of electro-mechanical noise. This sub-class of noise pollution or disturbance may produce a negative effect on a wide range of organisms. Variations in soundscapes as a result of natural phenomena and human endeavor may have wide-ranging ecological effects as many organisms have evolved to respond to acoustic cues that emanate primarily from undisturbed habitats.

Soundscape ecologists use recording devices, audio tools, and elements of traditional ecological and acoustic analyses to study soundscape structure. Soundscape ecology has deepened current understandings of ecological issues and established profound visceral connections to ecological data. The preservation of natural soundscapes is now a recognized conservation goal.
