Visualization for emotional sound

15 May

Every day we perceive sound from the outside of the world. Our ears undertake the heaviest “task” for hearing the sound. Have you ever thought about what sound looks like? Let’s go on a journey of sound visualization.
My visualization group of the course ARTS 2090 at UNSW created a graph for the visualization of emotional sound.  See the graph below:

The graph was created by Chang Jiang, Hoi Leong Lee, Isabelle Summerson.

In the graph, four colors distinguish four different emotions. The expression of the colors reflect the visual feeling that specific emotion potentially has. The way that the sound is visually presented is through the graph of sound frequency. We got the shape of the sound frequency through the steps: firstly, select and download the sounds according to the description in the Soundbank at UNSW, which match the best with the selected
emotions. Then, import the sound into the application called Soundbooth to get the credible sound wave. After we got all the sound, we use the application called Fireworks to form our purposed graph. We changed the color of different emotions. More importantly, we overlapped two sets of extreme opposite emotion in one graph to make a comparison and the overlapped areas shown in a different color reveal the similarities of the totally different emotions in the sense of hearing. However, interestingly we found that though the extreme opposite
emotions sound very different, it appears a lot similarities when we actually make it visible.

As for the critique on the data, the shape of the sound wave visualizes the sound we normally hear. We chose this data set to exploit the similarities between the patterns of emotions at opposite extremes. Moreover, the graph gives the public the understanding of the appearance of sound through using the sense of vision. The two main limitation of this visualization, firstly, limited data set cannot indicate the similarity pattern of the emotional sound and the result might vary if the sound produces by different people. Another one is that some of the psychological emotion cannot be visualized and presented through sound wave.
