This paper focuses on the use of spatial sound field analysis methods for acoustical investigations inside small enclosures. A measurement based approach is proposed for evaluating the sound propagation process within automotive spaces. Therefore the impulse responses of distinct loudspeakers were recorded at a dense microphone grid. At first the reliability of the recorded impulse response data set is checked, measurement error sources are identified and a compensation of temperature drift, which can occur in practice during the measurement task, is described. Applying these corrections provides an improved multichannel impulse response data set which is now ready to use for further investigations. Some examples of the results of a time domain simulation, based on these measurement data sets, are discussed.
