[AUDITORY] AW: Headphones For Online Experiments
Hi David,
a while back, I published data on a few pairs of circumaural headphones,
measured on several individuals. The results only speak for the specific
headphones in their respective working (or not working) order at the time,
but may give an idea of what to expect:

Canal Transfer Functions of Three Circum-Aural Headphones. J. Audio Eng.
Soc. 62, 315-323, 2014, http://www.aes.org/e-lib/browse.cfm?elib=17242
We also did a few interaural comparisons of the transducers (not on
individuals, again only representative for the specimens we used), which -
combined with the first data - may hint to what to (or not to) additionally
expect with dichotic presentation:

characteristics in binaural listening experiments: A case study. 143rd AES

Hi Bob - Do you or does anyone else on the list know if there are good data
to show the amount of within-subject variability in frequency response one
might get with placement and replacement of supra-aural or circumaural
headphones and how that within-subject variability might vary across
multiple people? I suspect many have measured it in the lab at one point or
another but published data or solid archival data would be helpful to get a
handle on that (one of several) technical issue.
Thanks,
Dave

On top of the technical specs issue there is the issue of variability in fit
for individual users. I suspect this may overshadow published frequency
response in many cases. Any ideas on how to control for that?
