· 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.
