Subject: Re: reverse engineering of acoustic sources From: beauchamp james w <jwbeauch(at)UX1.CSO.UIUC.EDU> Date: Sat, 31 Jan 2004 09:38:22 -0600Dear Georg, Thank you for your wonderful response to my question. I wonder if any of the mathematical solutions to this problem take into account directivity and room responses and whether they work for forced sustained vibrations (e.g., clarinet) as opposed to free vibrations (e.g., a drum).
