ABSTRACT
The goal of this research is improving alarm sound design, focusing on the paradox of noticeable versus pleasant sounds. The characteristics of annoying sounds correspond in large extend to the characteristics of noticeable sounds. Therefore it is difficult to design an alarm sound, which is noticeable, but not annoying. A lot of studies are conducted along aspects which make sounds annoying and several guidelines are described for designing noticeable alarm sounds. However, no data is conveyed about the combination of these characteristics linked to sound design. In this study an existing design process …show more content…

High frequency is also linked with harmonics, because a harmonic is a sound whose frequency is higher than the keynote of that sound observed by the ear. Furthermore, modulations contribute to an annoying sound, while discontinuous sounds provide a noticeable sound. This is conflicting, because if a sound has modulations it is not discontinuous as a result of the changes in tone.

So most of the characteristics of annoying and noticeable sounds are similar, whereby it is hard to design an alarm sound that is noticeable, but not annoying. All the corresponding characteristics are focused on type of sound. However, there are other factors which can influence the perception of annoyance and the noticeability of sound. These factors are particularly related to the context. Research of Philip (2009) also showed the relationship between the annoyance and noticeability of sound. She showed a significant correlation between the urgency rating and the annoyance rating of alarm sounds. The urgency rating can be linked to the noticeability of the alarm sound, which in essence points towards a relationship between the annoyance and noticeability of a sound. Yet, there are no papers with guidelines or methods to deal with this problem.

The overall goal of this research is improving alarm sound design, focusing on the balance between noticeable and pleasant sounds. The aim of this
