Not quite so. The authors of the paper describe Soundscape Ecology as being:

    [A]ll sounds, those of biophony, geophony, and anthrophony, emanating from a given landscape to create unique acoustical patterns across a variety of spatial and temporal scales.

And they contrast their definition to Acoustic Ecology by adding:

    Acoustic ecology, as introduced by Schafer (1977) and Truax (1999), is seen as complementary to traditional ecological concepts rather than situated within them. Broadly interdisciplinary, acoustic ecology studies the relationships and interactions among humans and sounds in an environment, including musical orchestrations, aural awareness, and acoustic design (Schafer 1977, Truax 1999). Acoustic ecology largely emphasizes human-centered inquiry rather than the larger socioecological systems approach taken here.
