Hi,

Sorry I have been trying to get to grips with I-Simpa recently and was wondering, what would be the best way to model how sound is emitted from a speaker cone. Would it be trying to use the balloon directivity or using geometry to shape the sound.

Kind Regards,

Harry Sawyer

Hi.

If it is for a speaker design you should use finite element method like this one:

http://acousto.sourceforge.net/

If you just want to apply a noise directivity balloon to a sound source you could write the directivity file using existing ones in this folder:

I-SIMPA\Directivities

And change the directivity property in source object along with the u,v,w orientation.
