ORE ON HEADPHONE MEASUREMENTS
The measurement obtained from a headphone will vary with headphone position and seal. In Headphone
Measurement Procedures - Frequency Response, Tyll Hertsens explains that he takes measurements at five
positions of the headphones on the measurement jig (that is, five on each side).
Figure 5 shows measurements taken at five headphone positions (one channel only) for an open headphone
(AKG K702), while Figure 4 shows measurements at five positions for a closed headphone (Audeze LCD-XC). We
recommend that you measure your own headphones at several different positions to establish how much
variation there is with position.
If you find that you get significant variation, you may wish to use your measurement program to generate an
average of several measurements. You may also find that, with practice at headphone positioning, you can
consistently get a "center" position measurement that is very close to this average.
