Abstract	Sounds are the result of one or several interactions between one or several objects at a certain place and in a certain environment; the attributes of every interaction influence the generated sound. The following factors influence users in human/computer interaction: the organization of the learning environment, the content of the learning tasks, the temporal share of the activity on the screen in proportion to the whole activity, the content of computer support, and the user friendliness of the interactive system. An experiment that investigated the effects of audio feedback showed that the results of a database query at the user interface with individually selective acoustic feedback were as good as with a previously adjusted standard interface without any acoustic feedback. The results of a second experiment showed that sound feedback significantly improves the performance of operating and controlling the simulation system of an assembly line with 38 difference sounds. A framework concept for the description of sounds is presented in which sounds can be represented as auditory signal patterns along several descriptive dimensions of objects interacting in an environment. The methodology can be demonstrated by the falling of a spherical elastic object onto a linear elastic beam. Rather than assigning an unchangeable sound to an object or operation, which results in a synthetic tone, a sound should be calculated in real time and be context sensitive. (Contains 19 references.)
