All measurements are done on a calibrated coupler
B&K 4153 (artificial ear) with the standard cone

YJ0304 above the adapter plate, type DB 0843.

 •

The pressure of the headband shall be 10N 

±

 1N.

 •

The RMS input voltage to the headphone is 0.5 V.

 •

The measurements are done with steady state sine
wave signals.

 •

The output impedance of the signal source shall be
<1 Ohm.
