Dan, I think the original can be found in Dave Green's Introduction to Hearing. Those of us in the lab at the time found it to be out of place with the book as a whole because the book was pretty rigorous. I have always wanted to do a version where the face looked like Dave, but then I would need to do something binaural to justify use of the figure.

Shub Sent: Monday, August 25, 2008 9:52 AM To: AUDITORY@xxxxxxxx Subject: Happy/Sad BMLD cartoon I am curious about the history of the cartoon which denotes the different stimulus configurations and the corresponding performance used in studies of binaural masking level differences. I did a quick web search for an example: This one looks like the version in Moore's book. My guess is Moore's artwork was original, but that he did not come up with the concept. I am curious as to who first conceptualize the BMLD with happy and sad faces. Thank you Dan
