• 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:
Temperature T=20
º C
Humidity H=50%rel
Atmospheric pressure P=approx. 100kPa
All data are influenced by temperature, humidity and static pressure.
