Classification of Rooms in Educational Buildings using different Noise Indicators
* Presenting author
Former studies provided different reasons for noise in schools and preschools. As such, room acoustic design and internal and external background noise sources are contributing to the overall noise level, in addition to the considerable proportion of noise which is generated by the children themselves. Current noise ratings mostly rely on single values, like dB(A), only, considering merely basic psychoacoustics. However, annoyance due to environmental noise is depending on a wider range of aspects which can be represented through psychoacoustic parameters. The aim of this work is to classify and to compare different types of rooms in educational buildings using room acoustic parameters and psychoacoustic parameters, both obtained from room acoustic measurements in silence and from in situ measurements in the presence of children, respectively. Results from different day care centres and primary schools in Aachen are presented in this instance.
