Re: [AUDITORY] Headphones For Online Experiments

["Eddins, David" <deddins@xxxxxxx>]

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?
