This experiment consists of listening to two different pieces of audio and ranking them according to which sound is more tense, pleasant or arousing.

Arousal is defined as the intensity of the emotions the person experiences. For example emotional states such as boredom, inactivity and sadness have low arousal; active, energetic affective states such as frustration and excitement have high arousal.

It is possible to leave the experiment at any time, by simply closing your browser, although we would appreciate if you could listen to a minimum of 6 pairs of audio samples. This experiment will require headphones and we also recommend that you adjust your volume configuration in order to get the ideal experience.
