This visualisation uses lines and glow features to highlight both the source of the sound and its way of reaching out to people. These features also disappear as people walk away as this resembles the attention being lost and therefore the intervention intervening less in the space. This visualisation seems to give the sound life as it shows it changing and reacting in ways relevant to its surroundings.
Ultimately this intervention was both successful and unsuccessful. I did obtain reactions and therefore the sound did intervene with the people and the space. However there were also a lot of times in which the sound did not have an effect, specifically when I used more environmental sounds. If these had been louder and therefore more obvious I may have had more success with them, but as it was these did not acheive the desired effect. However the reactions I did have were as expected and so the intervention that did occur still worked as intended.
