Dieser Jahresbericht der Campus IT der Fachhochschule Düsseldorf ist ein Beleg für das weitere quantitative und qualitative Wachstum dieser Einrichtung. Eine moderne IT ist essentiell für die Wettbewerbsfähigkeit der Hochschulen. Die Campus IT hat im Jahr 2012 gezeigt, dass sie diesen Auftrag verstanden hat und mit Drittmitteleinnahmen dafür gesorgt hat, das Bild der modernen IT Realität werden zu lassen. Diesem Ziel verschreiben wir uns weiterhin, so dass die Hochschule auch in Zukunft auf eine moderne Campus IT setzen kann.
Test environments in sound quality research often significantly differ from human’s everyday world. Hence the claim for ecological validity of such experiments is reasonable, but too vague in its bare formulation. The estimation of ecological validity requires theoretical knowledge about the meaning and the totality of factors influencing everyday listening and their interaction. Therefore the influence of “reality factors” on the sound evaluation of household appliances was investigated within the framework of nine experiments. These tests were performed in four different settings with varied reality degrees. The psychological realism and the perceived face validity of the tests were examined by means of interviews. The results reveal, on the one hand, that stimuli are perceived as more pleasant in everyday-like environments. The analysis of the relative judgments shows, on the other hand, that the influence of the experimental realism is moderated by a number of factors. These are the saliency and meaning of the sounds, differences between the assessed devices, and personality traits. The correlation and regression analysis confirms that the perceived sound character is widely independent from experimental realism. However, there is great empirical evidence, that valid assessments of sound quality require the reconstruction of everyday attention and action processes.
