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

130th AES Convention – London 13-16 May 2011

The results

The probe is not calibrated with an absolute level: every point of measure has its own level normalization and colour scale.

NEVERLESS

Growing the distance between source and receiver the lobe of the reflections becomes more relevant in comparison with the direct sound.


	[SUI DISEGNI]
	For the horizontal polare we synthesize 24 virtual microphones and for the 3D map we created 32 virtual microphones in the direction of the capsules.
