measuring output volume from headphones -- follow-up

[Robbin Miranda <raw25@xxxxxxxxxxxxxx>]

Thank you to those of you who responded to my previous question.  Your comments were extremely helpful!  Using a dummy head or coupler seems like a feasible option for the initial set-up of our two testing locations (we will be using the same type of headphones at each location).  However, I would also like to be able to quickly check the volume just prior to testing each participant (in case another user adjusts the computer's volume settings).  On my computer (Windows XP), all I have been able to find, even in the advanced settings, are scrollbars indicating the volume level.  Is there any way to check/adjust numerical values of the volume setting?

Thanks again,
Robbin
