77 8.6.7. Free-field compensated frequency response
78 8.6.7.1. Characteristics to be specified

79 The frequency response measured at the ear simulator of the HATS is compensated either

80 during the measurement by inverse filtering with the 0° free-field response of the HATS or by

81 subtracting (in dB) the 0° free-field frequency response of the HATS from the uncompensated

82 measured headphone response at the ear simulator of the HATS as a post-process operation.

83 8.6.7.2. Method of measurement

84  The headphone is brought under standard conditions for measurement, and a test signal

85 at the rated source voltage, is applied in series with the rated source impedance.

86  The frequency is then varied over at least the rated frequency range of the headphone

87 (see.8.6.6), and the sound pressure (level) at each frequency is noted for the right and
