Ooooh, this brings back some nasty memories of lying on my side whilst having mold goo shoved into my pinna! It's been at least 10 years or so but I do recall it being worthwhile to work with someone involved in plastic, er, reconstructive surgery. We did a few ears at U of Florida with some docs and then I tried to do a mold with hearing folks at Penn State a year later. The UF molds were much nicer. As for the dummy head, you can go down to LA and have a special effects group laser scan your own head and then give you a computer model for molding, hopefully with a material of similar acoustic impedance to skin and hair. Worth it just to freak out your office mates every once in a while or play hooky from work. ;-) David Prince Eric Benjamin wrote: Dear List, I am in the process of constructing a dummy head, and I would like to be able to make molds from my own ears and others' ears, and use them on the dummy head. Can someone on the list tell me how to do this, or refer me to a publication that tells how to do it? Eric Benjamin
