HDA200 is PTB approved. Physikalisch-Technische Bundesanstalt, Braunschweig, Germany. PTB is equivalent to the National Bureau of Standards.
HDA 200 Frequency Response Test Conditions
•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:
