Evolving Sonic Environment III is an acoustically-coupled analog neural network, consisting of a society of devices whose behaviour collectively changes in response to the pitch ascendancy or descendency that each one detects. In contrast to earlier versions of the project (which operated at much higher frequencies), humans will be able to participate more directly in the adaptation process by making sounds of their own.

Each device can output at any one time a rising and/or descending tone: however, if a device hears too much of one type of tone it may get 'bored' and slowly modify its behaviour. On the other hand, they may all coalesce in an equilibrium where they are all 'content' with the state of pitches in the room. This 'contentedness' may get disrupted when humans enter and start making their own sounds, thus perpetuating the evolving acoustic characteristics of the space.
