Abstract

In the context of soundscape evaluation, an area that has yet to be explored satisfactorily concerns faithful modelling and auralization of outdoor spaces. A common limitation of popular acoustic modelling techniques relates to source characterization, an aspect of which considered here is source directivity. In terms of auralization, source directivity may be linked to perceived spatial sound quality. In a preliminary listening test a selection of audio samples are auralized in a virtual free-field where the directivity pattern of the source is varied. The results confirm the significance of this characteristic on the acoustic perception, thus validating the extension of this research to more complex models.
