Translations:Sonification in practice/91/en

Considering that sound perception is time-based, sonification is by and large focused on rendering continuous data stream over time: this means that the input data of a sonification system could be also come from another domain, like the profile of a territory (geographical data) but all of them will be transferred onto a representation in time which is sound. Sound exists only in time, as variation of pressure detected by our eardrums and transformed into electrical signals in our brain, or broadly in our nervous system. Without getting into the depth of such a fascinating subject we need to clarify a couple of concepts before we move on. Even those who never played or created music know some of the characteristics of sound that we describe here.
