Headphone target measurement averages six manikin positions across three angles

Evidence

The steady-state frequency response of the left and right loudspeaker was measured separately with the manikin positioned at 0° and ±30° and smoothed in the frequency domain. All the measurements shown here are based on an average of 6 measurements (2 ears × 3 angles) with 1/3-octave smoothing. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1787
