Skycyclepilot said: That was going to be my next question - against which standard are these measurements compensated... Harman, Diffuse Field, etc... Click to expand...

Who did the measurement?

What system was used to make the measurement?

Was the headphone measurement system that was used based on standards intended to model human perception by modeling the correct impedance (of the human hearing system)?

How are the measurements done (how is placement determined over the fixture, etc.)?

Is the frequency response measurement shown a product of compensation?

If the frequency response measurement was compensated, why was it compensated, and what compensation curve was used?
