Subject: Re: [AUDITORY] Headphones For Online Experiments From: Vincent Koehl <vincent.koehl@xxxxxxxx> Date: Fri, 26 Jun 2020 09:01:26 +0200Hi all, We measured some years ago the placement-replacement variability (on a=20 dummy head) for supra-aural and circumaural headphones (4 models) and=20 its audible consequences. The paper can be found here : https://doi.org/10.1016/j.apacoust.2015.01.023 or alternatively here : https://hal.univ-brest.fr/hal-01119385 Best, Vincent Le 25/06/2020 =C3=A0 15:19, Eddins, David a =C3=A9crit=C2=A0: > 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 respon= se one might get with placement and replacement of supra-aural or circuma= ural headphones and how that within-subject variability might vary across= multiple people? I suspect many have measured it in the lab at one poin= t or another but published data or solid archival data would be helpful t= o get a handle on that (one of several) technical issue. > > Thanks, > > Dave > > David A.
