Abstract: Public spaces, such as parks, are an important part of urban design as they are source of recreation in daily life. Those spaces have a high impact on living comfort. This is why they are often subject to soundscape studies which are sometimes missing reproducibility. The auralization of virtual urban environments allows for controlled conditions in perception studies leading to more reliability. However, spatial stimuli of environmental sounds are not typically simulated due to their complexity. Thus, a method needs to be developed that allows to record calibrated dynamic sound scenarios for a hybrid use together with simulated signals in virtual scenes.For available spherical microphones, the direction-dependent sensitivities are often not available. Therefore, a spherical microphone is calibrated proposing two different measurement approaches. The measurement uncertainties are compared and discussed with regards to the spectral equalization for the use in auralizations.
