HRTFs are measured in anechoic space as angle-dependent transfer functions
Evidence
- The measurements are ideally made in an anechoic space using loudspeakers at specific vertical and horizontal angles with respect to the head. The data are in the form of the complex transfer function—the amplitude and phase vs. frequency responses, or the equivalent transformed version, the impulse response for each angle for incoming sound—hence the name. — Toole, Floyd E, Sound reproduction- the acoustics and…, 287
