•
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.
•
Climatic conditions:

Humidity
H=50%rel
Atmospheric pressure
P=approx. 100kPa
All data are influenced by temperature, humidity and static pressure.
