The study of soundscapes is about the experiences of sound, in contrast to the physical properties of sounds. It is about "Ear-mindedness"  and conscious awareness of the sounds that surround us. The first-person perspective and personal experience are central, making this approach essentially phenomenological. Ecology, on the other hand, is about the interaction between living plants or animals and their environment (including other plants and animals).
Johan Redstrom (Is Acoustic Ecology About Ecology?)
This quote interestingly references my project in a direct manner. Through the human interaction with the fountain, I aim to form a sound scape that encourages (or discourages, depending on the action) further interaction. The environmental effect of the user thus becomes and environmental effect on that user, in a feedback loop that forms within the space.
Redstrom goes on to point out that 'how we interact with our environment and how we experience it are intimately related'. As my project will attempt to create a feedback loop of interaction, it must be ensured that a (potential) user is encouraged to participate in that interaction, and create the loop. When many users exist in the space, multiple connected interactions may form leading to a cumulative effect on the sound scape.
