Car room sound field evaluating device, car room sound field evaluation method, cabin room sound field control device, and indoor sound field evaluation device

摘要

To provide a vehicle interior sound field evaluation device capable of accurately evaluating quietness of a vehicle compartment.SOLUTION: The vehicle interior sound field evaluation device detects the sound in a passenger compartment, extracts the spatial distribution feature of the virtual sound source including the strength of the virtual sound source on the basis of the detected sound in the passenger compartment so as to extract the spatial distribution feature of the sound field in the vehicle compartment, and evaluates the sound field in the vehicle compartment for the quietness of the vehicle compartment on the basis of the extracted spatial distribution feature of the sound field in the vehicle compartment.SELECTED DRAWING: Figure 13
