Re: Happy/Sad BMLD cartoon



Walt is (of course) right that the original came from Dave Green's book. Some people think the cartoon looks like Dave, leading to a number of "copy cat" illustrations. Alan Palmer used a photo of himself looking happy and sad in some of his presentations, and (also being graphically challenged) I stole the idea for a TICS article published in 2004. Presumably, with the advent of electronic publishing, one will soon be able to click on a video of the author either sighing in ecstasy or bursting into tears, depending on the particular binaural configuration.

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.

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
