Binaural headphone tests can replicate real-time loudspeaker listening

Evidence

Binaural techniques are loosely defined to be methods that aim to reproduce accurately ear canal signals recorded in a real acoustic scenario with a real subject, or to reproduce ear canal signals which would occur in a virtual world. This is done by recording sound from ear canals or by utilizing measured or modelled head-related transfer functions (HRTFs) and acoustic modelling of listening spaces. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1916 (#expands, via linked claim)

Loudspeaker-reproduced sound is always externalized but normally cannot deliver the binaural information separately to the ears. However, it is possible to process the left and right signals radiated by the loudspeakers so that the direct sounds arriving at the ears of a listener in the sweet spot are very close approximations to correct binaural signals—the acoustical crosstalk has been cancelled. When this is done well, the left stereo loudspeaker delivers sound almost exclusively to the left ear and the right stereo loudspeaker to the right ear. — Toole, Floyd E, Sound reproduction- the acoustics and…, 304 (#qualifies, via linked claim)
