Description
Higher-Order Ambisonics (HOA) is a widely used technique for sound field auralization; however, it presents inherent limitations, particularly in the trade-off between the number of transducers (microphones and loudspeakers) and the achievable timbral and spatial accuracy of the reproduced sound field.More recently, alternative approaches for the acquisition and reproduction of spatial room impulse responses have been developed. These include the Spatial Decomposition Method (SDM) is introduced, whose underlying theory is briefly reviewed in this work.This paper investigates differences in the quality of car interior auralization using impulse responses captured and reproduced with SDM and with HOA. The evaluation combines objective performance metrics with subjective listening tests to provide a comprehensive comparison of the two methods.
