Experimental analysis of spatial properties of the sound field inside a car employing a spherical microphone array

The post processing software

MATLAB script

Polar plot of the sound levels in the horizontal plane

Mesh map of the levels on a 360°x180° picture of the room

Dynamic plots

1st step

Import of WAV files containing the IRs obtained from the 32 virtual microphones

	The aim of the post processing is a movie representing the behaviour of the sound through a polar plot of the sound levels in the horizontal plane and a mesh map of the levels on a 360°x180° picture of the room.
	At first we import the wav files containing the Impulse Responses obtained from the 32 virtual microphones.
